One of the senior wizards Yee Sian was trapped in a maze during a mission. The maze has n * m cells, labelled from (0, 0) to (n-1, m-1). Starting at cell (0, 0), each time Yee Sian can only take one step, either to the right or down. We wish to find out the number of possible paths to the destination (n - 1, m - 1). A sample path is shown in the figure below.
Having learnt the technique of speeding up the pascal function through memoization, you decide to apply it here. If Yee Sian can walk out by himself (number of paths > 0), tell him how many ways there are. Otherwise, report to Grandwizard and send a rescue team.
Write a function num_of_paths that takes in two integers representing the number of rows (n) and columns (m) in a maze and returns an integer value of number of paths from cell (0, 0) to cell (n - 1, m - 1). The table and skeleton code are given to you. Your table is essentially a dictionary that stores (i, j): val pairs which indicate the number of paths from cell (0, 0) to cell (i, j).
Note: You may assume that all inputs n and m are valid. i.e. n > 0, m > 0.
Incomplete Code:
table = {} # table to memoize computed values
def num_of_paths(n, m):
# your code here
pass
Test Cases:
num_of_paths(1, 100) 1
num_of_paths(123, 1) 1
num_of_paths(3, 3) 6
num_of_paths(10, 10) 48620
num_of_paths(28, 56) 3438452994457305131328
Answers
table = {}
def num_of_paths(n, m):
# base cases
if n == 0 or m == 0:
return 1
if (n, m) in table:
return table[(n, m)]
# number of paths is the sum of paths from top and left cells
paths = num_of_paths(n - 1, m) + num_of_paths(n, m - 1)
table[(n, m)] = paths
return paths
print(num_of_paths(1, 100)) # 1
print(num_of_paths(123, 1)) # 1
print(num_of_paths(3, 3)) # 6
print(num_of_paths(10, 10)) # 48620
print(num_of_paths(28, 56)) # 3438452994457305131328
This function uses the fact that the number of paths to a cell is the sum of the number of paths from its top and left cells. The base cases are when either n or m is 0, in which case there is only 1 path (by definition). The function also uses a table dictionary to store the computed values to avoid recalculating them.

An automotive company tests the driving capabilities of its self driving car prototype. They Carry out the test on various types of roadways specifically a racetrack chill rack and dirt road what are the examples of fair or unfair practices
Answers
It is to be noted that testing a self-driving car prototype on various types of roadways, such as a racetrack, hill rack, and dirt road, can be considered fair practice. It would only be unfair practice if the lives and property of humans are put at risk during the testing.
What is unfair practice?Unfair practices are behaviors that are neither just or fair. It would be deemed unjust to treat someone differently because of their color or gender, for example. Cheating or violating regulations to get an edge over others is also included. To develop a fair and just society, it is critical to constantly treat people with fairness and respect.
In this scenario, it is evident that endangering human life and property is unethical behavior.

A table student consists of 5 rows and 7 columns. Later on 3 new attributes are added and 2 tuples are deleted. After some time 5 new students are added. What will be the degree and cardinality of the table?
Answers
Answer:
The degree of a table refers to the number of attributes (columns) it has. In the case you described, after the 3 new attributes are added, the degree of the table would be 7 + 3 = 10.
The cardinality of a table refers to the number of rows (tuples) it has. In the case you described, after 2 tuples are deleted, the cardinality of the table would be 5 - 2 = 3. After 5 new students are added, the cardinality would increase to 3 + 5 = 8.

Design and implement a program that reads a series of 10 integers from the user and prints their average. Read each input value as a string, and then attempt to convert it to an integer using the Integer.parseInt method. If this process throws a NumberFormatException (meaning that the input is not a valid number), print an appropriate error message and prompt for the number again. Continue reading values until 10 invalid integers have been entered.
Answers
Answer:
Explanation:
The following program was written in Java. It creates a loop that asks the user for numbers. If it can convert it to an integer it accepts it and adds it to the sum variable otherwise it ouputs that it is not a valid number. Once all 10 integers are added it prints the Average of the values entered.

Here, we investigate what happens when we change the value of a variable in a function. Your instructions are to
define a function that takes a single argument, adds 10 to that argument, and then prints it out (all inside the function!)
then, outside of the function, print out x, call your function using x as its argument, and print out x again
In total, x should be printed out 3 times. Did you get what you expected?

8 # call your function on x

Answers
Answer:
Observation:
The value of x remains the same in the main function
The value of x is incremented by 10 in the defined function
The program is as follows:
def Nm(x):
x += 10
print(x)
x = int(input("x: "))
print(x)
Nm(x)
print(x)
Explanation:
The explanation is as follows:
This defines the function
def Nm(x):
This increments x by 10
x += 10
This prints x (the first print statement)
print(x)
The main begins here; This gets input for x
x = int(input("x: "))
This prints x (the second print statement)
print(x)
This calls the function
Nm(x)
This prints x (the third print statement)
print(x)
Assume that x = 5;
The first print statement (in the function) prints 15 i.e. 5 + 10 = 15
The second and third print statements (in the main function) prints 5, the exact value of x

Explanation:
Pharming involves redirecting users to a fraudulent website even when the user has typed in the correct address in the web browser. An individual can accomplish this by changing the hosts file of the web address that the user is trying to access or by exploiting a DNS server error. Both of which will allow the individual to convince the victim that they are accessing the website that they were trying to access, but instead they have been redirected to a website that looks identical but is owned by the individual. The victim then enters their valuable and private information into the website and the individual can see it all and use it as they wish. Usually, this is done to steal banking information.

"Words are way more edgy when you replace the letter i with an exclamation point!
Write the function exclamations that takes a string and then returns the same string with every lowercase i replaced with an exclamation point. Your function should:
Convert the initial string to a list
Use a for loop to go through your list element by element
Whenever you see a lowercase i, replace it with an exclamation point in the list
Return the stringified version of the list when your for loop is finished"

The goal of this problem is to cover all roads with cameras. A camera placed at a station can cover all the roads connected to it. For example, if we place a camera at station 0, the roads (or edges) (0,3) and (0,8) are covered. Note: the edges (0,3) and (3,0) are the same. We want to find all solutions that can cover a network. For example, one solution is to place a camera at each station will cover all roads. In G2, which has 10 stations, this solution is the set {0,1,2,3,4,5,6,7,8,9} or [True, True, True, True, True, True, True True, True, True). Another solution for G2 is {2, 3, 5, 8} or [False, False, True, True, False, True, False, False, True, False, False]. Any road/edge in G2 is connected to one of these 2 or 3 or 5 or 8. Therefore, {2,3,5, 8} is one of the solutions we look for. The code below is almost complete in printing out all solutions, i.e. sets of stations that cover an entire network. What you need to do for this problem is modyfing the is_coverage function, which returns True if the solution is a coverage, and False if it is not. At this time, it's just a placeholder, which always returns True. This is obviously incorrect. You need to fix it. [42]: def is_coverage (solution, G): return True def get_stations(s): return set([i for i in range(len(s)) if s[i]==True]) def cover(G, solution, i): if i==len(solution): if is_coverage (solution, G): print(get_stations ( solution)) else: solution[i] = True cover(G, solution, i+1) solution[i] = False cover(G, solution, i+1)
