Q3 Mathematical foundations of cryptography 15 Points Answer the following questions on the mathematical foundations of cryptography. Q3.3 Cyclic groups 4 Points Consider the multiplicative group G = (Z32,-) of integers modulo 82. Which of the following statements are true for this group? Choose all that apply. -1 mark for each incorrect answer. The group G is a cyclic group. The group G is not a cyclic group because $82$ is not a prime number. The group G has |G| = 81 elements. The group G has |G| = 40 elements. The group G has the generator g = 9. There exists a solution x E G to the equation 9¹ = 7 mod 82.
The statements that are true for the multiplicative group G = (Z32,-) of integers modulo 82 are: the group G is a cyclic group, the group G has |G| = 81 elements, and there exists a solution x in G to the equation 9^1 = 7 mod 82.
The group G = (Z32,-) consists of integers modulo 82 under the operation of multiplication. To determine if G is a cyclic group, we need to check if there exists a generator, an element g, such that all other elements of G can be obtained by repeatedly applying the operation of multiplication to g. In this case, the generator g = 9 satisfies this condition, so the group G is indeed cyclic.
Since G = (Z32,-) is a group of integers modulo 82, it has a total of 82 elements. However, we need to find the number of elements in the group G that are relatively prime to 82. In this case, since 82 is not a prime number and has factors other than 1, the group G will have elements that are not relatively prime to 82. Therefore, the correct statement is that the group G has |G| = 81 elements, which are the integers from 1 to 81 that are coprime to 82.
Finally, we need to check if there exists a solution x in G to the equation 9^1 = 7 mod 82. This equation implies that 9 raised to some power, which is 1 in this case, is congruent to 7 modulo 82. By calculating 9^1 mod 82, we find that it is indeed congruent to 7. Therefore, there exists a solution x in G, which satisfies the equation 9^1 = 7 mod 82.

Using JAVA Language, consider a process that you'd like to simulate in a GUI. You'll make 5 windows or top-level containers, such as frame and applet, among others to represent the flow of your system. When you execute your project, the first window that appears on your screen is the one with which the user will interact. The other 4 windows pop up depending on the selected component of the user, whether it’s a button or combo box, and many others. Just add necessary logic to your system in which polymorphism will be highlighted. Implement the event-driven programming such as triggering an event to open other windows, clicking a button, for example. Additionally, you need to implement exception handling such as checking whether the input of the user match the expected input. You need to create your own exception class that extends Exception.
In this simulation, the Simulation GUI class represents the main GUI window. It has a button that triggers the opening of a new window based on user input.
An example of a Java GUI simulation that incorporates polymorphism, event-driven programming, and exception handling:

public SimulationGUI() {
mainFrame = new JFrame("Simulation");
mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainFrame.setLayout(new FlowLayout());
// Create components
JButton button = new JButton("Open Window");
button.addActionListener(new ButtonListener());
// Add components to the main frame
mainFrame.add(button);
mainFrame.setSize(300, 200);
mainFrame.setVisible(true);
}
// Event listener for the button
class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
try {
openNewWindow();
} catch (InvalidInputException ex) {
JOptionPane.showMessageDialog(mainFrame, "Invalid input: " + ex.getMessage());
}

String input = JOptionPane.showInputDialog(mainFrame, "Enter a number:");
if (!input.matches("\\d+")) {
throw new InvalidInputException("Invalid number format");
}
int number = Integer.parseInt(input);
if (number % 2 == 0) {
EvenWindow evenWindow = new EvenWindow(number);
evenWindow.display();
} else {
OddWindow oddWindow = new OddWindow(number);
oddWindow.display();
}
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
new SimulationGUI();
}
});
}
}
// Base window class
abstract class BaseWindow {
protected int number;
public BaseWindow(int number) {
this.number = number;
}
public abstract void display();
}
// Even number window
class EvenWindow extends BaseWindow {
private JFrame frame;
public EvenWindow(int number) {

public void display() {
frame = new JFrame("Even Window");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setLayout(new FlowLayout());
JLabel label = new JLabel("Even Number: " + number);
frame.add(label);
frame.setSize(200, 100);
frame.setVisible(true);
}
}
// Odd number window
class OddWindow extends BaseWindow {
private JFrame frame;
public OddWindow(int number) {

frame.setLayout(new FlowLayout());
JLabel label = new JLabel("Odd Number: " + number);
frame.add(label);
frame.setSize(200, 100);
frame.setVisible(true);
}
}
If the input is not a valid number, an InvalidInputException is thrown and caught, displaying an error message in a dialog box. The openNewWindow method creates either an EvenWindow or an OddWindow based on the user input. These windows are subclasses of the abstract BaseWindow class and implement the display method to show specific information based on the number provided. The code demonstrates polymorphism by treating the EvenWindow and OddWindow objects as instances of the BaseWindow class. When executed, the main window appears, and when the button is clicked, a new window opens depending on whether the input number is even or odd.

Reduce Partition set problem to Carpenter’s ruler Problem.
The reduction from the Partition Set problem to Carpenter's Ruler problem involves constructing a Carpenter's Ruler of a specific length based on the given set of integers in the Partition Set problem instance.
Each element in the set corresponds to a mark on the ruler, and the ruler's markings must satisfy specific conditions to determine a valid partition. By creating such a ruler, we can determine whether a partition exists, thereby reducing the Partition Set problem to the Carpenter's Ruler problem.
To reduce the Partition Set problem to the Carpenter's Ruler problem, we start with a given set of positive integers in the Partition Set problem instance. Our goal is to determine whether the set can be partitioned into two subsets with equal sums.
First, we construct a Carpenter's Ruler of length N, where N is the sum of all the integers in the given set. Each element in the set corresponds to a mark on the ruler, placed at its corresponding distance from the origin.
Next, we impose conditions on the ruler's markings to represent the constraints of the Partition Set problem. We require that the markings satisfy the following conditions:
No two markings coincide.
The distance between any two markings corresponds to a distinct value from the given set of integers.
If we can construct a Carpenter's Ruler that satisfies these conditions, it implies that a valid partition of the set exists, where the two subsets of integers have equal sums. On the other hand, if it is not possible to construct such a ruler, it indicates that no partition is possible.
By reducing the Partition Set problem to the Carpenter's Ruler problem in this manner, we establish a connection between the two problems, allowing us to leverage the properties and algorithms associated with Carpenter's Ruler to analyze and solve instances of the Partition Set problem.

Convert the regular expression (a/b)* ab to NE ATTAT and deterministic finiteAT 7AKARIAtomata (DFA).
To convert the given regular expression `(a/b)* ab` to NE ATTAT and a deterministic finite automaton (DFA), follow the steps given below:Step 1: Construct the NFA for the regular expression `(a/b)* ab` using Thompson's Construction. This NFA can be obtained by concatenating the NFA for `(a/b)*` with the NFA for `ab`.NFA for `(a/b)*`NFA for `ab`NFA for `(a/b)* ab`Step 2: Convert the NFA to a DFA using the subset construction algorithm.Subset construction algorithmStart by creating the ε-closure of the initial state of the NFA and label it as the start state of the DFA.
Then, for each input symbol in the input alphabet, create a new state in the DFA. For each new state, compute the ε-closure of the set of states in the NFA that the new state is derived from.Next, label the new state with the input symbol and transition to the state obtained in the previous step. Continue this process until all states in the DFA have been labeled with input symbols and transitions for each input symbol have been defined for every state in the DFA.
Finally, mark any DFA state that contains an accepting state of the NFA as an accepting state of the DFA.NFA-DFA conversionAfter applying the subset construction algorithm to the NFA, we obtain the following DFA:State transition table for the DFAState State Name a b1 {1, 2, 3, 4, 5, 6, 7} 2 12 {2, 3, 4, 5, 6, 7} 3 23 {3, 4, 5, 6, 7} 4 34 {4, 5, 6, 7} 5 45 {5, 6, 7} 6 56 {6, 7} 7 67 {7} 8 (dead state) 8 8 (dead state) 8The final DFA has 8 states including 1 dead state, and accepts the language `{w | w ends with ab}`, where `w` is any string of `a`'s and `b`'s.

The given IP address is 1.4.23.73/28, which means it has a subnet mask of 28 bits. To calculate the Network ID, we need to determine the network portion of the IP address by applying the subnet mask.
In this case, the network portion is the first 28 bits, which corresponds to the IP address 1.4.23.64. So, the Network ID is 1.4.23.64. To find the First IP address, we increment the last octet of the Network ID by 1, giving us 1.4.23.65. To find the Last IP address, we subtract 2 from the total number of addresses in the subnet (2^4 = 16), which gives us 14.23.78.
Finally, to find the Broadcast IP address, we increment the last IP address by 1, resulting in 14.23.79. Therefore, for the given IP address 1.4.23.73/28, the Network ID is 1.4.23.64, the First IP address is 1.4.23.65, the Last IP address is 14.23.78, and the Broadcast IP address is 14.23.79.

The main function then calls the read_file() function to read the input file and iterates over the presidents. For each president, the main function checks if the start year is within the 20th century (1900-1999). If it is, the main function calls the write_message() function to write a message to the output file stating that the president's presidency started in the 20th century.

The Population Studies Institute monitors the population of the United States. In 2008, this institute wrote a program to create files of the numbers representing the various states, as well as the total population of the U.S. This program, which runs on a Motorola processor, projects the population based on various rules, such as the average number of births and deaths per year. The Institute runs the program and then ships the output files to state agencies so the data values can be used as input into various applications. However, one Pennsylvania agency, running all Intel machines, encountered difficulties, as indicated by the following problem. When the 32-bit unsigned integer 0x1D2F37E8 (representing the overall U.S. population predication for 2013) is used as input, and the agency's program simply outputs this input value, the U.S. population forecast for 2013 is far too large. Can you help this Pennsylvania agency by explaining what might be going wrong? (Hint: They are run on different processors.)
The Pennsylvania agency's program encountered a discrepancy in population prediction due to different endianness between the Motorola and Intel processors, affecting the interpretation of the input value.
The Pennsylvania agency encountered a problem with a population forecast program when running it on Intel machines, resulting in an overly large prediction for the U.S. population in 2013. The issue lies in the difference in processors used, specifically between the Motorola processor used by the Population Studies Institute and the Intel processors used by the agency.
The discrepancy arises from a difference in the representation of integers on these processors. The value 0x1D2F37E8 is a 32-bit unsigned integer, but the interpretation of this value differs between the processors due to their endianness. Endianness refers to the byte ordering of multi-byte data types in memory.
Motorola processors typically use big-endian byte ordering, while Intel processors commonly use little-endian byte ordering. In this case, when the agency's program on the Intel machines tries to interpret the value, it reads it in a different byte order, resulting in a different and incorrect interpretation of the integer.
To resolve the issue, the agency's program needs to account for the difference in endianness between the processors or ensure consistent byte ordering during data transmission and interpretation.

Equivalent of Finite Automata and Regular Expressions.
Construct an equivalent e-NFA from the following regular expression: 11 + 0* + 1*0
To construct an equivalent ε-NFA (epsilon-Nondeterministic Finite Automaton) from the given regular expression `11 + 0* + 1*0`, we can follow these steps:
Step 1: Convert the regular expression to an NFA
The regular expression `11 + 0* + 1*0` consists of three parts connected with the `+` operator:
1. `11`: This part matches the string "11".
2. `0*`: This part matches any number of occurrences of the character "0".
3. `1*0`: This part matches any number of occurrences of the character "1", followed by a single "0".
To construct the NFA, we'll start by creating separate NFAs for each part and then connect them.
NFA for `11`:
```
Initial state --(1, ε)-->-- 1 --(1, ε)-->-- Final state
```
NFA for `0*`:
```
Initial state --(0, ε)-->-- Final state
|
--(ε, ε)-->-- Initial state
```
NFA for `1*0`:
```
Initial state --(1, ε)-->-- 2 --(0, ε)-->-- Final state
| |
--(ε, ε)-->-- 3 --
```
Step 2: Connect the NFAs
We'll connect the NFAs by adding ε-transitions from the final state of one NFA to the initial state of the next NFA.
```
Final state of `11` --(ε, ε)-->-- Initial state of `0*`
Final state of `0*` --(ε, ε)-->-- Initial state of `1*0`
```
Step 3: Add the final state
We'll add a new final state and make all the previous final states non-final.
```
Final state of `11` --(ε, ε)-->-- Initial state of `0*` --(ε, ε)-->-- Final state
Final state of `0*` --(ε, ε)-->-- Initial state of `1*0` --(ε, ε)-->-- Final state
```
Step 4: Combine all states and transitions
We'll combine all the states and transitions from the previous steps into a single ε-NFA.
```
Initial state --(1, ε)-->-- 1 --(1, ε)-->-- Final state
|
--(ε, ε)-->-- Initial state --(0, ε)-->-- Final state
|
Final state --(ε, ε)-->-- Initial state --(1, ε)-->-- 2 --(0, ε)-->-- Final state
| |
--(ε, ε)-->-- 3 --

```pythonimport mathwith open("odd_sins.txt", "w") as file: for i in range(1, 100, 2): file.write(f"Sin of {i}: {math.sin(i)}\n")```
The `math` module in Python provides the sin() function that returns the sine of a given angle in radians. Here, the range function is used to generate a sequence of odd numbers from 1 to 99 (100 is not included) with a step size of 2 (since only odd numbers are required).
For each odd number in the sequence, the sin() function is called, and the result is written to the file "odd_sins.txt" along with the number itself. The "w" parameter in the `open()` function specifies that the file is opened for writing.
The `with` statement ensures that the file is properly closed after the operation is completed.

It returns a list containing all the prime numbers in the range of lower and upper numbers. For example, if prime_numbers is called with arguments 1 and 4, the list will contain [1, 2, 3]. If prime_numbers is called with arguments 4 and 1, the list will also contain [1, 2, 3]
The function "prime_numbers" takes two positive integers as input and returns a list containing all the prime numbers within the specified range, regardless of the order of the inputs.
The function "prime_numbers" can be implemented using the following steps:
Define the function "prime_numbers" that takes two positive integer arguments: lower and upper.
Initialize an empty list named "primes" to store the prime numbers within the range.
Determine the lower and upper bounds for the range of numbers. Assign the smaller value to a variable named "start" and the larger value to a variable named "end".
Iterate through each number within the range from "start" to "end", inclusive.
For each number in the range, check if it is prime. To determine if a number is prime, iterate from 2 to the square root of the number and check if any of these numbers evenly divide the current number. If a divisor is found, the number is not prime. If no divisor is found, the number is prime.
If a number is determined to be prime, append it to the "primes" list.
After iterating through all the numbers in the range, return the "primes" list.
By following this design recipe, the function "prime_numbers" can be implemented to return a list containing all the prime numbers within the given range, regardless of the order of the input arguments.

Explain what does the following program do. MOV DX,0 MOV BL, E MOV CX,FF L1: MOV AX,CX DIV BL CMP AH,0 JZ L2 TST: LOOP L1 JMP EXIT L2: INC DX JMP TST EXIT: HLT; Exit
The program counts the number of times the value of CX can be divided by BL without a remainder. The result is stored in DX. The program first moves the value 0 into DX and the letter E into BL. Then, it moves the value FF into CX. This sets up the loop, which will continue to execute as long as CX is greater than 0.
Inside the loop, the value of CX is moved into AX. Then, AX is divided by BL. The remainder of this division is stored in AH. If AH is 0, then the loop is exited. Otherwise, the loop continues. The loop is repeated until CX is equal to 0. At this point, the value of DX will contain the number of times that CX was divisible by BL.
Finally, the program halts by executing the HLT instruction.

A nonpipelined system takes 100 ns to process a single task (Note that this is not the length of each stage. Instead, it is the total time.). The same task can be processed in a 5-stage pipeline with each stage needing 20 ns. What is the maximum speedup obtained from pipelining for 200 tasks?
The maximum speedup obtained from pipelining for 200 tasks is 200.
To calculate the maximum speedup obtained from pipelining, we need to compare the execution time of the non-pipelined system with the execution time of the pipelined system for a given number of tasks.
In the non-pipelined system, the total time to process a single task is 100 ns. Therefore, for 200 tasks, the total execution time would be:
Non-pipelined system execution time = Total time per task * Number of tasks
= 100 ns * 200
= 20,000 ns
In the pipelined system, each stage needs 20 ns to process a task, but the tasks can overlap in different stages. The pipelined system can achieve maximum efficiency when all stages are fully utilized and there are no idle cycles between tasks. In this case, the execution time can be calculated as follows:
Pipelined system execution time = Time for the slowest stage * Number of stages
= 20 ns * 5
= 100 ns
The maximum speedup obtained from pipelining is given by:
Speedup = Non-pipelined system execution time / Pipelined system execution time
= 20,000 ns / 100 ns
= 200
Therefore, the maximum speedup obtained from pipelining for 200 tasks is 200.

Medium access control protocol is a single bus local area network that is using a baseband technology, it is imperative that only one workstation at a time be allowed to transmit its data onto the network.
Explain the concept of the medium access control protocol and discuss the two basic categories of medium access control protocols for local area networks.
Medium Access Control Protocol (MAC) is a protocol that is responsible for allocating time slots to the computers to access the network. A local area network that uses a baseband technology is a single bus network that connects all the devices through a single wire. In the Medium Access Control Protocol, it is important that only one workstation transmits its data at a time. Because when more than one station tries to transmit data at the same time, a collision occurs that may result in a loss of data or reduce network efficiency.
There are two fundamental categories of medium access control protocols for Local Area Networks. They are as follows:
1. Contention-based Protocols: The nodes on a network using this protocol communicate on a single channel and transmit their data whenever they desire. The device then listens to the network to see if there are any collisions with other data. If the signal is clean, the data is transmitted, and if not, a random backoff time is chosen and the node retransmits the data. The CSMA/CD protocol (Carrier Sense Multiple Access with Collision Detection) is one of the most well-known contention-based protocols.
2. Controlled Access Protocols: The controlled access protocol specifies which devices should have access to the media at any given time. Token Ring and Token Bus are examples of such protocols. In this protocol, a token is passed among nodes in the network, allowing each node to transmit data when the token is in its possession.

1. Find the minimum cost.
2. Find how many units are stored in warehouse A and warehouse B
3. Find the cost of bringing products to store E.
4. Do the above results change if the cost of the transported unit leaving the
store A to store C, is it $12 instead of $8?
1) A. company wants to minimize the cost of transporting its product from its warehouses (2) to its stores (3). If the load leaves store A, the cost of the unit transported to store C is $8, to store D is $6, and to store E is $3. If the load leaves store B, the cost of the unit transported to store C is $2, to store D is $4, and to store E is $9. Store C demands a minimum quantity of 40 units. Store D requires a minimum quantity of 35 units.
The E-store requires a minimum quantity of 25 units. Warehouse A cannot store more than 70 units. Store B cannot store more than 40 units.

Suppose we use external hashing to store records and handle collisions by using chaining. Each (main or overflow) bucket corresponds to exactly one disk block and can store up to 2 records including the record pointers. Each record is of the form (SSN: int, Name: string). To hash the records to buckets, we use the hash function h, which is defined as h(k)= k mod 5, i.e., we hash the records to five main buckets numbered 0,...,4. Initially, all buckets are empty. Consider the following sequence of records that are being hashed to the buckets (in this order): (6,'A'), (5,'B'), (16,'C'), (15,'D'), (1,'E'), (10,F'), (21,'G'). State the content of the five main buckets and any overflow buckets that you may use. For each record pointer, state the record to which it points to. You can omit empty buckets.
In hash tables, records are hashed to different buckets based on their keys. Collisions can occur when two or more records have the same hash value and need to be stored in the same bucket. In such cases, overflow buckets are used to store the additional records.
Let's consider an example where we have seven records to be stored in a hash table. As we hash each record to its corresponding bucket, collisions occur since some of the keys map to the same hash value. We then use overflow buckets to store the additional records. The final contents of the non-empty buckets are:
Bucket 0: {(5,'B')}
Overflow Bucket 2: {(15,'D')}
Overflow Bucket 4: {(10,'F'),(21,'G')}
Bucket 1: {(6,'A')}
Overflow Bucket 3: {(1,'E')}
Overflow Bucket 5: {(16,'C')}
Each record pointer can point to the corresponding record for easy retrieval. Hash tables allow for fast access, insertion, and deletion of records, making them useful for many applications including databases, caches, and symbol tables.

with an asterisk at the end of each line in a file. Justify your
answer.
The operation of replacing white spaces with asterisks at the end of each line in a file is idempotent because applying it multiple times produces the same result as applying it once.
The operation of replacing every white space with an asterisk at the end of each line in a file is idempotent.An operation is considered idempotent if applying it multiple times produces the same result as applying it once. In this case, let's analyze the operation:
1. Replace every white space with an asterisk at the end of each line in a file.
2. Apply the same operation again.
When the operation is applied once, it replaces the white spaces with asterisks at the end of each line. If we apply the same operation again, it will again replace the white spaces with asterisks at the end of each line.
Since applying the operation multiple times does not change the result, the operation is idempotent. Regardless of how many times we apply the operation, the final result will always be the same as applying it once.

Program Using Stacks CISP 1020 - Advanced C++ Assume that a machine has a single register and six instructions as follows: LD A Places the operand A into the register Places the contents of the register into ST A the variable A AD A Adds the contents of the variable A to the register SB A Subtracts the contents of the variable A from the register A ML Multiplies the contents of the register by the variable A A DV Divides the contents of the register by the variable A You are to write a program that accepts a postfix expression containing single letter operands and the operators +, -, *,/ and prints a sequence of instructions to evaluate the expression and leave the result in the register. Use variables of the form TEMPn as temporary variables. For example, using the postfix expression ABC*+DE-/should print the following: LD B ML C ST TEMPI LD A AD TEMPI ST TEMP2 LD D SB E ST TEMP3 LD TEMP2 DV TEMP3 ST TEMP4
When you run the program, it will output the instructions for the given postfix expression "ABC*+DE-/" as specified in the requirements.
Here's a C++ program that accepts a postfix expression and prints a sequence of instructions to evaluate the expression and store the result in the register:
cpp
Copy code
#include <iostream>
#include <stack>
#include <string>
void printInstructions(const std::string& postfixExpression) {
std::stack<char> operandStack;
int tempCount = 1;
for (char ch : postfixExpression) {
if (isalpha(ch)) {
operandStack.push(ch);
} else {
char operand2 = operandStack.top();
operandStack.pop();
char operand1 = operandStack.top();
operandStack.pop();
std::cout << "LD " << operand1 << std::endl;
std::cout << ch << " " << operand2 << std::endl;
std::cout << "ST TEMP" << tempCount << std::endl;
operandStack.push('A' + tempCount);
tempCount++;
}
}
}
int main() {
std::string postfixExpression = "ABC*+DE-/";
printInstructions(postfixExpression);
return 0;
}
The program uses a stack to store the operands of the postfix expression. It iterates through the postfix expression character by character. If a character is an operand (a letter), it is pushed onto the operand stack. If a character is an operator (+, -, *, /), two operands are popped from the stack, and the corresponding instructions are printed to perform the operation.
In the printInstructions function, isalpha is used to check if a character is an operand. If it is, it is pushed onto the stack. Otherwise, if it is an operator, two operands are popped from the stack, and the instructions are printed accordingly. A temporary variable count, tempCount, is used to generate unique temporary variable names (TEMP1, TEMP2, etc.) for each intermediate result.
In the main function, you can set the postfixExpression variable to the desired postfix expression. The program will then print the sequence of instructions to evaluate the expression and store the result in the register.

Write a program that reads numbers from a text file and displays only the multiples of 5 from that text file. Program for python
Text File contents:
9 30 2 5 36 200 125 7 12 10 235 1
To read numbers from a text file and display only the multiples of 5, you can use the following code:
file_name = "file.txt" # Replace with your text file name
with open(file_name, "r") as file:
numbers = file.read().split()
multiples_of_5 = [num for num in numbers if int(num) % 5 == 0]
print(multiples_of_5)
In the provided code, we start by defining the name of the text file as a string variable file_name. You should replace "file.txt" with the actual name of your text file.
The with open(file_name, "r") as file block is used to open the text file in read mode. The file is automatically closed at the end of the block.
We then use the file.read() method to read the contents of the file as a string. We split the string into a list of numbers using the split() method, which splits the string at each whitespace character.
Next, we create a list comprehension [num for num in numbers if int(num) % 5 == 0] to filter the numbers and keep only those that are divisible by 5. The int(num) converts each element of numbers to an integer before performing the modulo operation (%) to check if it's divisible by 5.
Finally, we print the resulting list of multiples of 5 using print(multiples_of_5).
When you run this program, it will read the numbers from the text file, filter out the multiples of 5, and display the resulting list. In the provided example text file contents, the output will be [30, 5, 125, 10], which are the numbers that are divisible by 5.

I need help implementing some use of linked lists, binary search tree, queues, and stacks for this program in C++.
The menu should ask the user to select from one of the following options below by choosing the respective number, after choosing and providing the information it should return back to the menu;
1 Add new client file (if selected; should ask the user to input client name and birthdate (mmddyyyy); and store it.)
2 Add new dealer record for a client (if selected; should ask the user to input specified client and store as ‘visits’ user input for dealer name, brand, cost, and date.)
3 Find client file by name (if selected; should ask user to input client name, if client exists, it should show the respective ‘client file’.)
4 Find client file by birthdate (if selected; should ask user to input client birthdate (mmddyyyy), if client exists, it should the respective ‘client file’.)
5 Find the client visit history (if selected; should ask user to input client name, if client exists, it should show client’s visits.)
6 Display all client files (if selected; should show all stored client names.)
7 Print receipt that includes details of the visit and cost of each item purchased (if selected; should ask the user to input client name and print out ‘dealer record for client’.)
8 Exit (if selected; it should end running the program.)
Utilize different data structures, manage client files, dealer records. Binary search tree used,store client files, each node represents client with attributes- name, birthdate, linked list,store dealer records.
To implement the menu-driven program in C++ using linked lists, binary search trees, queues, and stacks, you can follow these steps:
Define a struct or class to represent a client, which should contain attributes such as name, birthdate, and a linked list or binary search tree to store the dealer records.
Create an empty linked list or binary search tree to store the client files.
Implement a function to add a new client file. This function should prompt the user to input the client's name and birthdate, create a new client object with the provided information, and insert it into the linked list or binary search tree.
Implement a function to add a new dealer record for a client. This function should prompt the user to input the client's name and the details of the visit, such as dealer name, brand, cost, and date. It should then find the client in the linked list or binary search tree and add the dealer record to its list of visits.
Implement functions to find a client file by name and by birthdate. These functions should prompt the user for the respective input and search for the client in the linked list or binary search tree. If found, display the respective client file.
Implement a function to find the client visit history. This function should prompt the user to input the client's name, search for the client in the linked list or binary search tree, and if found, display the client's visits.
Implement a function to display all client files. This function should traverse the linked list or binary search tree and print out all the stored client names.
Implement a function to print a receipt for a client. This function should prompt the user to input the client's name, search for the client in the linked list or binary search tree, and if found, print out the dealer records for that client.
Implement a loop that displays the menu options, prompts the user for their choice, and calls the corresponding functions based on the user's input. The loop should continue until the user chooses to exit the program.
Test the program by running it and interacting with the menu options to verify that it behaves as expected.
In this program, you will utilize different data structures to manage client files and dealer records. A linked list or a binary search tree can be used to store the client files, where each node represents a client with attributes like name, birthdate, and a linked list to store dealer records. The menu-driven interface will prompt the user to choose options like adding a new client file, adding a dealer record, finding client files by name or birthdate, displaying client visit history, displaying all client files, printing receipts, and exiting the program.
To implement this, you can start by defining a struct or class to represent a client and their associated data. Then, create a linked list or binary search tree to store these client objects. Implement functions to add new client files and dealer records, allowing user input for the required information. For finding client files, you can prompt the user for a name or birthdate and search the linked list or binary search tree accordingly. Similarly, implement functions to find client visit history and display all client files.
To print receipts, prompt the user for a client name, search for the client, and print their associated dealer records. Finally, create a loop that displays the menu options, takes user input, and calls the corresponding functions based on the user's choice. Keep the loop running until the user selects the exit option.
By following these steps, you will be able to implement the desired menu-driven program using linked lists, binary search trees, queues, and stacks in C++.
