StdID: 252185 Question 1: 2 Marks The Fibonacci sequence defined by F=1,1,2,3,5,8,13,21,34,55,89,...N where the ith term is given by F = F₁-1 + F₁-2 Code has already been provided to define a function named fibGen that accepts a single input into the variable N. Add code to the function that uses a for loop to generate the Nth term in the sequence and assign the value to the output variable fib with an unsigned 32-bi integer datatype. Assume the input N will always be greater than or equal to 4. Note the value of N (StdID) is defined as an input to the function. Do not overwrite this va in your code. Be sure to assign values to each of the function output variables. Use a for loop in your answer.

Answers

Answer 1

Certainly! Here's the MATLAB code for the fibGen function that generates the Nth term in the Fibonacci sequence using a for loop:

function fib = fibGen(N)

   fib = uint32(zeros(N, 1)); % Initialize output variable as unsigned 32-bit integer array

   fib(1) = 1; % First term of the Fibonacci sequence

   fib(2) = 1; % Second term of the Fibonacci sequence

   

   for i = 3:N

       fib(i) = fib(i-1) + fib(i-2); % Generate the i-th term using the previous two terms

   end

end

You can call this function by passing an input value for N, and it will return the Nth term of the Fibonacci sequence as an unsigned 32-bit integer. Remember that the input N should be greater than or equal to 4.

For example, to find the 10th term in the Fibonacci sequence, you can use the following code:

fibTerm = fibGen(10);

disp(fibTerm);

This will display the value of the 10th term in the Fibonacci sequence, which is 55.

Answers

Here is a Python program that takes a range from the user and displays all the odd numbers within that range:

start, end = input("Enter the range (start, end): ").split(',')

start = int(start.strip())

end = int(end.strip())

if start % 2 == 0:

   start += 1

for num in range(start, end+1, 2):

   print(num, end=' ')

The program prompts the user to enter a range in the format "(start, end)" using the input() function. The input is split into two parts, start and end, using the split() method. The strip() method is used to remove any extra spaces. The start and end values are converted to integers using the int() function. If the start value is even, it is incremented by 1 to make it odd.

A for loop is used to iterate over the range from start to end+1, incrementing by 2 in each iteration to only consider odd numbers. Each odd number is printed using the print() function, with the end parameter set to a space to display the numbers on the same line.The program ensures that the range includes both the start and end values and only displays odd numbers within that range.

Answers

The given Python program prompts the user to enter a number between 1 and 3. It then reads the input and checks if the number is within the desired range using a while loop. If the number is not between 1 and 3, it displays the message "Nope." and prompts the user to enter the number again. Once a valid number is entered, it uses if-elif statements to determine the corresponding fruit based on the input number: 1 for "Apples", 2 for "Oranges", and 3 for "Bananas". The program then prints the corresponding fruit.

If the user enters 5 when prompted, the output will be "Nope." The while loop condition `x<1 or x>3` will evaluate to True because 5 is greater than 3. Therefore, the program will enter the loop, print "Nope.", and prompt the user to enter the number again. This will continue until the user enters a number between 1 and 3.

If the user enters 3 when prompted, the output will be "Bananas". The program will enter the if-elif chain and execute the code under the condition `x==3`, which prints "Bananas".

If the user enters 1 when prompted, the output will be "Apples". The program will enter the if-elif chain and execute the code under the condition `x==1`, which prints "Apples".

If the user enters -2 when prompted, there will be no output. The while loop condition `x<1 or x>3` will evaluate to True because -2 is less than 1. Therefore, the program will enter the loop, print "Nope.", and prompt the user to enter the number again. This will continue until the user enters a number between 1 and 3.

Answers

We count the number of males younger than 25 years, the number of females in pclass 3 who survived, and draw a boxplot of fare for male passengers in pclass 2 and 1 using ggplot.

To accomplish Task 2, we need to perform several operations on the data from the "train.csv" file. First, we count the number of males who are younger than 25 years. This involves filtering the data based on gender and age, and then counting the matching records.

Next, we count the number of females in pclass 3 who survived. This requires filtering the data based on gender, passenger class, and survival status, and then counting the matching records.

Lastly, we draw a boxplot using ggplot to visualize the fare distribution for male passengers in pclass 2 and 1. This involves filtering the data based on gender and passenger class, and then using ggplot's boxplot functionality to create the visualization.

By performing these operations on the data from the "train.csv" file, we can obtain the required information and visualize the fare distribution for male passengers in pclass 2 and 1.

Below is a schema for an HR database:
employee(empid, fname, lname, managerid, departmentid, employee_rank)
It's an employee table, which has employee id, first name, last name, manager id (which is an employee id), department id, and employee_rank, such as VP, CEO, SVP, etc.
Using SQL, answer this question (write a SQL query that answers this question) [tip: use a recursive query].
10. For employee 42, find the path-of-managers directly to the CEO?

Answers

The query will traverse the hierarchy of managers until it reaches the CEO, storing the path of managers in a result set.

To find the path of managers directly to the CEO for employee 42 in the HR database, a SQL query using recursive query functionality can be used.

In SQL, we can use a recursive query to find the path of managers directly to the CEO for a specific employee. The recursive query will traverse the employee table, starting from the given employee, and follow the managerid column to find the manager of each employee until it reaches the CEO.

Here is an example SQL query to find the path-of-managers for employee 42:

sql

WITH RECURSIVE manager_path AS (

 SELECT empid, fname, lname, managerid, 1 AS level

 FROM employee

 WHERE empid = 42

 UNION ALL

 SELECT e.empid, e.fname, e.lname, e.managerid, mp.level + 1

 FROM employee e

 INNER JOIN manager_path mp ON e.empid = mp.managerid

)

SELECT * FROM manager_path;

Explanation of the query:

The query starts with a recursive CTE (Common Table Expression) named manager_path. It begins with the anchor member, which selects the details of employee 42 and assigns a level of 1 to it.

The recursive member is then defined, which joins the employee table with the manager_path CTE based on the managerid column. This recursive member selects the details of each manager, increments the level by 1, and continues the recursion until it reaches the CEO.

The final SELECT statement retrieves all rows from the manager_path CTE, which represents the path-of-managers directly to the CEO for employee 42. The result will include the empid, fname, lname, managerid, and level for each manager in the path.

By executing this query, you will obtain the desired path-of-managers for employee 42, starting from the employee and following the chain of managers until reaching the CEO.

An Exam Center needs to maintain a database of 3000 students' IDs who registered in a professional certification course. The goal is to find rapidly whether or not a given ID is in the database. Hence, the speed of response is very important; efficient use of memory is not important. No ordering information is required among the identification numbers.

Answers

The most appropriate data structure for the task of maintaining a database of 3000 students' IDs and quickly finding whether a given ID is in the database would be a Hash Table.

A Hash Table offers fast access to data based on a key, making it an ideal choice for efficient search operations. In this case, the student IDs can serve as keys, and the Hash Table can provide constant time complexity on average for lookup operations. The speed of response is crucial, and a well-implemented Hash Table can quickly determine whether or not a given ID is present in the database.

The efficient use of memory is not important in this scenario, which aligns with the Hash Table's ability to handle large amounts of data without significant memory considerations. As no ordering information is required among the identification numbers, a Hash Table provides a convenient and efficient solution for this specific task.

Explain answer in detail
Part 5: TCP Congestion Control Assume a TCP connection is established over a 1.2 Gbps link with an RTT of 4 msec. Assume that when a group of segments is sent, only a Single Acknowledgement is returned (i.e. cumulative). We desire to send a file of size 2MByte. The Maximum segment length is 1 Kbyte. Congestion occurs when the number of Bytes transmitted exceeds the Bandwidth x Delay product (expressed in Bytes). Two types of TCP congestion control mechanisms are considered. For each type sketch the congestion window vs. RTT diagram. a. TCP implements AIMD (with NO slow start) starting at window size of 1 MSS. When congestion occurs, the window size is set to half its previous value. Will congestion occur? If Yes, when? If No, why not? Find the throughput of the session and the link utilization in this case. b. TCP implements slow start procedure ONLY (i.e. No congestion avoidance phase). Again it starts with a window size of 1 MSS and doubles every RTT. When congestion occurs, the window size is reset to 1 MSS again. Will congestion occur? If Yes, when? If No why not? Find the throughput of the session and the link utilization in this case. Useful Series: sigma_i=1^n i=n(n+1) / 2

Answers

a. In TCP AIMD with No Slow Start, congestion will not occur, and the throughput of the session is 524288 Kbytes/sec with a link utilization of 0.436.

b. In TCP Slow Start Only, congestion will occur after the third RTT, and the throughput of the session is 174762 Kbytes/sec with a

In order to determine whether congestion will occur and analyze the throughput and link utilization for each type of TCP congestion control mechanism.

let's go through the calculations and steps for each scenario:

a. TCP AIMD (Additive Increase Multiplicative Decrease) with No Slow Start:

- Maximum segment length (MSS) = 1 Kbyte = 1000 bytes

- Bandwidth = 1.2 Gbps = 1200 Mbps = 1200000 Kbps

- RTT (Round-Trip Time) = 4 msec

- File size = 2 MByte = 2 * 1024 * 1024 bytes = 2097152 bytes

To determine whether congestion occurs, we need to compare the number of bytes transmitted to the Bandwidth x Delay product.

Bandwidth x Delay product = (1200000 Kbps / 8) * (4 msec) = 600000 Kbyte

Since the file size is 2097152 bytes, which is less than the Bandwidth x Delay product, congestion will not occur in this case.

The throughput of the session can be calculated using the formula: Throughput = File size / RTT.

Throughput = 2097152 bytes / 4 msec = 524288 Kbytes/sec.

The link utilization can be calculated by dividing the throughput by the link capacity: Link utilization = Throughput / Bandwidth.

Link utilization = 524288 Kbytes/sec / 1200000 Kbytes/sec = 0.436.

b. TCP Slow Start Only:

- Maximum segment length (MSS) = 1 Kbyte = 1000 bytes

- Bandwidth = 1.2 Gbps = 1200 Mbps = 1200000 Kbps

- RTT (Round-Trip Time) = 4 msec

- File size = 2 MByte = 2 * 1024 * 1024 bytes = 2097152 bytes

In the slow start procedure, the window size starts with 1 MSS and doubles every RTT until congestion occurs. When congestion occurs, the window size is reset to 1 MSS again.

To determine whether congestion occurs, we need to compare the number of bytes transmitted to the Bandwidth x Delay product.

Bandwidth x Delay product = (1200000 Kbps / 8) * (4 msec) = 600000 Kbyte

At the beginning, the window size is 1 MSS = 1000 bytes.

For the first RTT, the window size doubles to 2000 bytes.

For the second RTT, the window size doubles to 4000 bytes.

For the third RTT, the window size doubles to 8000 bytes.

Since the window size (8000 bytes) is greater than the Bandwidth x Delay product (600000 bytes), congestion will occur after the third RTT.

The throughput of the session can be calculated by dividing the file size by the number of RTTs until congestion:

Throughput = File size / (Number of RTTs until congestion * RTT)

Throughput = 2097152 bytes / (3 * 4 msec) = 174762 Kbytes/sec.

The link utilization can be calculated by dividing the throughput by the link capacity: Link utilization = Throughput / Bandwidth.

Link utilization = 174762 Kbytes/sec / 1200000 Kbytes/sec = 0.145.

In summary:

a. In TCP AIMD with No Slow Start, congestion will not occur, and the throughput of the session is 524288 Kbytes/sec with a link utilization of 0.436.

b. In TCP Slow Start Only, congestion will occur after the third RTT, and the throughput of the session is 174762 Kbytes/sec with a

1 How is exception handling different from just a "go-to" or a series of if statements? Identify an run time event that might need to be handled by exceptions.

Answers

Exceptions allow for graceful error handling and separation of error-handling code from normal flow of program. They provide a mechanism to catch and handle specific types of errors, promoting code readability.

Exception handling is a programming construct that allows developers to handle runtime errors and exceptional situations in a structured manner. It involves using try-catch blocks to catch and handle specific types of exceptions. When an exceptional event occurs, such as a division by zero or an invalid input, an exception is thrown, and the program flow is transferred to the corresponding catch block. This allows for specific error-handling code to be executed, providing a graceful way to handle errors and preventing the program from crashing or producing incorrect results.

In contrast, using "go-to" statements or a series of if statements to handle errors can lead to unstructured and error-prone code. With "go-to" statements, the program flow can jump to any arbitrary location, making it difficult to understand the control flow and maintain the code. A series of if statements can become complex and convoluted, especially when handling multiple error conditions.

An example of a runtime event that might need to be handled by exceptions is file I/O operations. When reading from or writing to a file, various exceptions can occur, such as a file not found, permission denied, or disk full. By using exception handling, these exceptions can be caught and handled appropriately. For instance, if a file is not found, the program can display an error message to the user or prompt them to choose a different file. Exception handling provides a way to gracefully handle such situations and prevent the program from crashing or producing unexpected results.

To determine the types and well-typedness of the given expressions, let's analyze each of them: 1. `cheetah (tiger (7,False))`

This expression is well-typed. The `tiger` function has the type `(Int, Bool) -> Integer`, and the `cheetah` function takes an argument of type `a` and a tuple of type `(Char, a)`. In this case, `tiger (7,False)` has the type `Integer`, and it matches the second argument of `cheetah`. Therefore, the most general type of this expression is `cheetah :: (Char, Integer) -> String`.

2. `filter panther []`

  This expression is not well-typed. The `filter` function expects a function as the first argument and a list as the second argument. However, `panther` is not a function but has the type `Float -> Bool`. Therefore, there is a type mismatch between the expected function type and the actual type of `panther`.

3. `jaguar 'R' 17`

  This expression is well-typed. The `jaguar` function takes two arguments: a tuple of type `(Char, a)` and a `Float`. In this case, `'R'` has type `Char`, and `17` has type `Num a => a`, which means it can be any numeric type. Therefore, the most general type of this expression is `jaguar :: (Char, a) -> Float -> [Bool]`.

4. `(lion,"cub", True)`

  This expression is not well-typed. The tuple `(lion, "cub", True)` has elements of different types (`lion` is a function and `"cub"` is a `String`). Tuples in Haskell require all elements to have the same type, so this expression results in a type error.

5. `map tiger`

  This expression is not well-typed. The `map` function expects a function as the first argument and a list as the second argument. However, `tiger` has the type `(Int, Bool) -> Integer` and not a list type.

6. `Park (panther, 7)`

  This expression is not well-typed. The `Park` constructor expects two arguments: the first argument should be of type `(a, Int)`, and the second argument should be a list of type `[a]`. In this case, `panther` has the type `Float -> Bool`, which does not match the expected type of `(a, Int)`.

7. `[lion, lion, lion]`

  This expression is well-typed. The list contains elements of type `lion`, which has the type `String -> Locale`. Therefore, the most general type of this expression is `[lion] :: [String -> Locale]`.

8. `Zoo`

  This expression is not well-typed. `Zoo` is a data constructor of the `Locale` type, which expects arguments of specific types. To create a `Zoo` value, you need to provide an `Integer`, `Float`, and a tuple of `(Bool, Char)`. Without these arguments, it results in a type error.

Note: The provided type signatures for the functions and data constructors don't match the usual Haskell syntax and conventions. If you have the correct type signatures, it would be easier to determine the types of the expressions accurately.

What is(are) the pre-condition(s) for binary search? a. The data should be sorted according to the search comparison algorithm order. b. The data must be kept in a random accessible collection. c. The data must be able to be compared according to the search comparison algorithm. d. The data must be in primitive data structures

Answers

The correct answer is a. The data should be sorted according to the search comparison algorithm order.

Binary search is an efficient searching algorithm used to find a specific item in a sorted collection of elements. In order for binary search to work correctly, the data must be sorted based on the search comparison algorithm order. This means that the data must be arranged in either ascending or descending order before applying binary search.

The other options mentioned in the question are not pre-conditions for binary search. Keeping the data in a random accessible collection and being able to compare the data according to the search comparison algorithm are requirements for implementing binary search, but they are not pre-conditions. Similarly, the data does not necessarily have to be stored in primitive data structures to perform binary search.

The correct answer is a. The data should be sorted according to the search comparison algorithm order.

(10%) Given the language L = {a³nbn: n ≥ 1} (a) Find the context-free grammar for the L (b) Find the s-grammar for the L

Answers

(a) The context-free grammar for the language L = {a³nbn: n ≥ 1} is:

S -> aaSbb | abb

(b) The s-grammar for the language L = {a³nbn: n ≥ 1} is:

S -> aaS | b

The non-terminal symbol S represents the starting symbol of the grammar. The production rules state that S can be replaced with either "aaSbb" or "abb". The production "aaSbb" generates three 'a' followed by three 'b', while the production "abb" generates one 'a' followed by two 'b'. By applying these production rules recursively, we can generate strings in the language L where the number of 'a's is three times the number of 'b's.

The s-grammar is a simplified form of the context-free grammar where all the production rules have a single non-terminal symbol on the right-hand side. In this case, the non-terminal symbol S can be replaced with either "aaS" or "b". The production "aaS" generates two 'a' followed by the non-terminal symbol S, allowing for the generation of multiple groups of 'a's. The production "b" generates a single 'b'. By applying these production rules recursively, we can generate strings in the language L with any number of 'a's followed by the same number of 'b's, where the number of 'a's is a multiple of three.

4. Consider the statement: If x and y are integers such that x +y > 5, then x > 2 or y > 2. (a) Write the symbolic form of the statement using quantifiers. (b) Prove or disprove the statement. Specify which proof strategy is used.

Answers

(a) Symbolic form of the statement using quantifiers:

∀x∀y [(x,y ∈ Z ∧ x + y > 5) → (x > 2 ∨ y > 2)]

(b) To prove the statement, we can use a direct proof strategy.

Direct proof:

Assume that x and y are integers such that x + y > 5. We want to show that x > 2 or y > 2.

We'll consider two cases:

Case 1: x ≤ 2

If x ≤ 2, then x + y ≤ 2 + y. Since x + y > 5, we have 2 + y > 5, which implies y > 3. Therefore, y > 2.

Case 2: y ≤ 2

If y ≤ 2, then x + y ≤ x + 2. Since x + y > 5, we have x + 2 > 5, which implies x > 3. Therefore, x > 2.

Since we've shown that either x > 2 or y > 2 in both cases, the statement is proved.

STRINGS Implement a program that reads two strings from the user and merges them into a new string, as the following examples show. The program should then print the resulting string. Examples. string 1 = "ccccc" string 2 = "ggggg" result string 1 = "XYZ" string 2 = "cccccc" result = "XcYcZcccc" = "cgcgcgcgcg" string 1 = "00000000" string 1 = "" string 2 = "TBA" string 2 = "ABC" result = "OTOBOA00000" result = "ABC" Notes. You can assume that no string entered by the user is longer than 100 characters. Define your strings as arrays of characters. However, you must use pointer arithmetic when processing the strings. You are not allowed to to use array notation anywhere other than when defining the strings. • You are not allowed to use the string.h library.

Answers

By avoiding the use of the string.h library and relying on pointer arithmetic, you can develop a program that efficiently merges strings and produces the desired output.

To implement a program that merges two strings into a new string, you can follow these steps:

Define two character arrays to store the input strings. Use pointer arithmetic to manipulate the strings throughout the program.

Read the two input strings from the user. You can use the scanf function to read the strings into the character arrays.

Create a new character array to store the resulting merged string. Allocate enough memory to accommodate the merged string based on the lengths of the input strings.

Iterate through the first string using a while loop and copy each character into the merged string using pointer arithmetic. After copying each character, increment the pointers accordingly.

Repeat the same process for the second string, copying each character into the merged string.

Once both strings are copied into the merged string, append a null character '\0' at the end to mark the end of the string.

Finally, print the merged string using the printf function.

By following these steps, you can implement a program that reads two strings from the user, merges them into a new string, and prints the resulting string.

In the implementation, it's important to use pointer arithmetic instead of array notation when manipulating the strings. This involves using pointers to iterate through the strings and perform operations such as copying characters or incrementing the pointers. By using pointer arithmetic, you can efficiently process the strings without relying on the array notation.

Pointer arithmetic allows you to access individual characters in the strings by manipulating the memory addresses of the characters. This provides flexibility and control when merging the strings, as you can move the pointers to the desired positions and perform the necessary operations. It's important to handle memory allocation properly and ensure that the merged string has enough space to accommodate the combined lengths of the input strings.

By avoiding the use of the string.h library and relying on pointer arithmetic, you can develop a program that efficiently merges strings and produces the desired output. Remember to handle edge cases, such as when one of the strings is empty or when the merged string exceeds the allocated memory.

Answers

Data structures and algorithms are fundamental concepts in computer science and programming. They form the foundation on which all software is built. In this report, we will explore the concept of data structures and algorithms, their types, and how they are used in programming.

Data Structures

A data structure is a way of organizing data in a computer so that it can be used efficiently. There are several commonly known data structures including:

Arrays

An array is a collection of elements of the same type stored together in memory. Each element in an array is accessed using an index value.

Stacks

A stack is a last-in-first-out (LIFO) data structure. It has two primary operations: push (add an item to the top of the stack) and pop (remove an item from the top of the stack).

Queues

A queue is a first-in-first-out (FIFO) data structure. It has two primary operations: enqueue (add an item to the back of the queue) and dequeue (remove an item from the front of the queue).

Linked Lists

A linked list is a collection of nodes, each containing a value and a pointer to the next node. The first node is called the head of the list.

Algorithms

An algorithm is a set of instructions used to solve a particular problem. Algorithms can be represented using flowcharts, pseudocode, or actual code. There are different types of algorithms including:

Sorting Algorithms

Sorting algorithms are used to arrange a collection of items in a particular order. Some popular sorting algorithms include bubble sort, selection sort, and merge sort.

Searching Algorithms

Searching algorithms are used to find a specific item in a collection of items. Some popular searching algorithms include linear search, binary search, and hash tables.

Analyzing Algorithms

To analyze an algorithm, we need to determine its efficiency, which is typically measured in terms of time and space complexity. Time complexity refers to the amount of time taken to run an algorithm, while space complexity refers to the amount of memory used by an algorithm.

Big O Notation

The Big O notation is used to describe the upper bound of an algorithm's time or space complexity. It is expressed as a function that represents the worst-case scenario for the algorithm's performance. Some commonly used Big O notations include:

O(1) - Constant Time

This means that the algorithm takes the same amount of time regardless of the size of the input data.

O(n) - Linear Time

This means that the algorithm takes time proportional to the size of the input data.

O(n^2) - Quadratic Time

This means that the algorithm takes time proportional to the square of the input data.

Python Code Samples

Here are some code samples in Python for the data structures discussed earlier:

Arrays

my_array = [1, 2, 3, 4, 5]

print(my_array[0]) # Output: 1

Stacks

class Stack:

   def __init__(self):

       self.items = []

   def push(self, item):

       self.items.append(item)

   def pop(self):

       return self.items.pop()

my_stack = Stack()

my_stack.push(1)

my_stack.push(2)

print(my_stack.pop()) # Output: 2

Queues

from collections import deque

my_queue = deque()

my_queue.append(1)

my_queue.append(2)

print(my_queue.popleft()) # Output: 1

Linked Lists

class Node:

   def __init__(self, value):

       self.value = value

       self.next = None

class LinkedList:

   def __init__(self):

       self.head = None

   def add(self, value):

       new_node = Node(value)

       if self.head is None:

           self.head = new_node

       else:

           current = self.head

           while current.next is not None:

               current = current.next

           current.next = new_node

my_list = LinkedList()

my_list.add(1)

my_list.add(2)

print(my_list.head.value) # Output: 1

Which comparison should be used?
Integer score1 = 20;
Integer score2 = 30;
int score3 = 40;
a.
score1 < score2
b.
score1 >= score3
c.
score2 == score3
d.
score1 == score2

Answers

The correct comparison to use in this case would be option A: score1 < score2.

This is because score1 has a value of 20, and score2 has a value of 30. The < operator compares the values of score1 and score2, and since 20 is less than 30, the comparison score1 < score2 would evaluate to true.

Option B (score1 >= score3) and option C (score2 == score3) are not valid comparisons because score3 is an int while score1 and score2 are Integer objects. However, it is possible to compare Integer objects with int values using auto-unboxing, but it is generally not recommended due to potential NullPointerExceptions.

Option D (score1 == score2) would only evaluate to true if both score1 and score2 are pointing to the same Integer object with a value of 20. This is because == compares object references rather than their values. Therefore, unless both score1 and score2 were initialized as score1 = score2 = 20, the comparison score1 == score2 would be false.

For calculating the average refrigerator efficiency for each brand, using the fridge DF Data Frame as input, the Relational Grouped Dataset has a method called avg() which is used for calculating per-group averages. It works similarly to count() except that avg() requires the names of the columns to be averaged. To show the first five rows of the ordered data, the function show(5) is used. The groupBy() function is used to group the DataFrame using the specified column names. The avg() function is used to calculate the average of the specified columns. The orderBy() function is used to sort the data in ascending or descending order based on the column name specified. The descending order is used here as per the question.

Therefore, the set of Data Frame functions that best answers exercise 4 of lab 6 is groupBy, avg, orderBy, show(5) option (d).

PREDICATE AND QUANTIFIER LOGIC
1. What is a categorical sentence?
2. Identify the following as either a singular or a categorical sentence, or a propositional function: The terms and principles of x serve their purpose.
3. Pick out and symbolize the propositional function in the following: McPhee will be elected president.

Answers

Categorical sentences are those that relate two classes or categories of things, and the predicate provides information about the subject and is associated with the verb. Singular, Categorical or propositional functions can be symbolized as a predicate or variable. Propositional functions can be thought of as a rule that assigns a truth value to a given instance of a predicate.

1. Categorical sentence Categorical sentences are the ones that relate two classes or categories of things. The category of things referred to in the sentence is the subject, and the predicate provides information about the subject and is associated with the verb in the sentence. A simple example of a categorical sentence is 'All humans are mortal' or 'All dogs bark.'

2. Singular, Categorical or propositional function?The given sentence "The terms and principles of x serve their purpose." is a categorical sentence. The sentence contains the subject "the terms and principles of x," and the predicate provides information about the subject by stating "serve their purpose." Therefore, the sentence is a categorical sentence.

3. Symbolize the propositional function The propositional function in the given sentence "McPhee will be elected president" can be symbolized as a predicate. This predicate can be represented as P(x), where P stands for predicate and x is the variable. The variable represents the entity being discussed in the sentence.In this sentence, 'x' can be replaced by 'McPhee.' Thus, the propositional function can be symbolized as P(McPhee), where P(McPhee) = McPhee will be elected president. The propositional function can be thought of as a rule that assigns a truth value (True or False) to a given instance of a predicate.

A new pandemic has struck the world: Food inflation The novel coronavirus disease (COVID-19) pandemic was pushed off global front pages last fortnight by food inflation. Food prices have leaped 75 per cent since mid-2020, the Food and Agriculture Organization (FAO) assessed. In India, rural consumer food price has doubled in the year through March 2022, according to the All India Consumer Price Index (CPI) by the National Statistical Office (released April 12). At 13 per cent, the countrys annual wholesale inflation was at the highest in a decade. Food and fuel prices played a major role. Such is the impact of inflation that the World Food Program (WFP), currently running one of its most expansive food relief operations in recent history, made a desperate appeal for further funding. Because, food inflation has significantly increased the cost of its day-today relief: Its paying $71 million (Rs 544 crore) more per month now for the same operation level. In the context of the Russia-Ukraine war, energy security came into focus. The world has been debating how the fossil fuel disruption will derail the planets efforts to reduce greenhouse gas emissions to stop global warming and resultant climate change. Fuel price is already rising and adding to overall costs of everything, including food production and transportation. But, the war has also disrupted food grain supply and circulation further adding to the demand-supply equation. Extreme weather events continue to affect large swathes of areas growing food and thus bringing down overall production. To sum up, the most fundamental survival need is at stake. This crisis exposes the globalized worlds another fault line. When the COVID-19 pandemic struck, an interconnected globalised world suddenly woke up to a situation where every country retreated and scrambled for self-protection; expectedly the rich world jealously colonised all resources needed to fight the pandemic leaving the rest helpless. The food sector is also interconnected and interdependent, though perilously. WFP calls its aftermath a "seismic hunger crisis" gripping the world. In Africa and west Asia, the hunger crisis has already set in. The World Bank has warned that each percentage point increase in food prices would push an additional 10 million people into extreme poverty. The impact of food inflation is impacting the worlds poor and developing countries the most, because most of these countries are also food importers. For instance, some 50 countries, mostly poor countries, depend on Ukraine and Russia for wheat, a staple grain. (Source: DowntoEarth, April 2022)Question 1) Define what food inflation is.
