Alice lent money to Bob, and they created a document stating the amount of money Alice lent. This document has been encrypted using the symmetric algorithm AES. Alice and Bob are the only ones who know the key used for encryption. After a while, Alice asked Bob for her money back, and Bob gave her $10. at this point, Alice said the amount of money was $1000, but Bob denied it. They went to the police station and got their copies of the encrypted document. The officer asks Bob and Alice to decrypt the document for further investigation. Surprisingly, Alice's document stated the lent money was $1000. In addition, Bob's document noted the amount of money was $10. according to this scenario, answer the following questions: 1. Why are both documents different? As you know, both copies matched at the agreement time. 2. Clearly, there is a problem in the protocol used; propose another protocol that may not be vulnerable to such a problem.
The reason for the difference between the two documents is that Alice has changed the original document after symmetric it and before the officer asks Bob and Alice to decrypt it.
This is done by changing the value of the money amount from $10 to $1000 in Alice's original document.2. One protocol that may not be vulnerable to such a problem is the digital signature protocol. This protocol involves the use of a hash function, a private key, and a public key. In this protocol.
Alice will sign the document with her private key, and Bob will verify it with Alice's public key. If the document is changed, the hash value of the document will also change, and the digital signature will become invalid. Thus, any change to the document will be detected, and the protocol will be secure.

In C++, Please show me how to do the code for main.cpp and finance.cpp. Also please label which code is for finance.cpp and main.cpp
Summary
Typically, everyone saves money periodically for retirement, buying a house, or for some other purposes. If you are saving money for retirement, then the money you put in a retirement fund is tax sheltered and your employer also makes some contribution into your retirement fund. In this exercise, for simplicity, we assume that the money is put into an account that pays a fixed interest rate, and money is deposited into the account at the end of the specified period. Suppose that a person deposits R dollars' m times a year into an account that pays I % interest compounded m times a year for t years. Then the total amount accumulated at the end of t years is given by
R
(1+r/m)mt-1 r/m
For example, suppose that you deposit $500 at the end of each month into an account that pays 4.8% interest per year compounded monthly for 25 years. Then the total money accumulated into the account is 500[(1+0.048/12)300 - 1]/(0.048/12) = $289,022.42
On the other hand, suppose that you want to accumulate S dollars in t years and would like to know how much money, m times a year, you should deposit into an account that pays I % interest compounded m times a year. The periodic payment is given by the formula
S(r/m)/(1 + r/m) - 1
Here's an example implementation of `finance.cpp` and `main.cpp` in C++:
**finance.cpp**:
```cpp
#include "finance.h"
double calculateTotalAmount(double R, double I, double m, double t) {
double r = I / 100;
double amount = R * pow((1 + r/m), m*t) - R;
return amount;
}
double calculatePeriodicPayment(double S, double I, double m, double t) {
double r = I / 100;
double payment = (S * r/m) / (1 + r/m - 1);
return payment;
}
```
**finance.h**:
```cpp
#ifndef FINANCE_H
#define FINANCE_H
#include <cmath>
double calculateTotalAmount(double R, double I, double m, double t);
double calculatePeriodicPayment(double S, double I, double m, double t);
#endif // FINANCE_H
```
**main.cpp**:
```cpp
#include <iostream>
#include "finance.h"
int main() {
double R, I, m, t;
double S;
// Get user input
std::cout << "Enter the deposit amount per period (R): ";
std::cin >> R;
std::cout << "Enter the interest rate (I): ";
std::cin >> I;
std::cout << "Enter the compounding frequency per year (m): ";
std::cin >> m;
std::cout << "Enter the number of years (t): ";
std::cin >> t;
// Calculate and display total amount accumulated
double totalAmount = calculateTotalAmount(R, I, m, t);
std::cout << "Total amount accumulated: $" << totalAmount << std::endl;
// Get user input for target amount
std::cout << "\nEnter the target amount (S): ";
std::cin >> S;
// Calculate and display periodic payment required
double periodicPayment = calculatePeriodicPayment(S, I, m, t);
std::cout << "Periodic payment required: $" << periodicPayment << std::endl;
return 0;
}
```
In this code, `finance.cpp` defines two functions: `calculateTotalAmount` and `calculatePeriodicPayment`, which perform the necessary calculations based on the given formulas. `finance.h` provides function declarations for these functions.
`main.cpp` includes the `finance.h` header and implements the main program logic. It prompts the user for input values for deposit amount per period (R), interest rate (I), compounding frequency per year (m), and number of years (t). It then calls the `calculateTotalAmount` function to calculate and display the total amount accumulated.
After that, it prompts the user for the target amount (S) and calls the `calculatePeriodicPayment` function to calculate and display the periodic payment required.

It also handles the case of dividing by zero and displays an appropriate message:
function result = divideNumbers(input1, input2)
if input2 == 0
result = [];
disp('!!! Can''t divide by 0 (zero) !!!');
else
result = max(input1, input2) / min(input1, input2);
end
end
This function checks if input2 is equal to zero. If it is, it assigns an empty array [] to the result variable and displays the error message "!!! Can't divide by 0 (zero) !!!" to the user.
Otherwise, it calculates the division max(input1, input2) / min(input1, input2) to get the desired result.

Because L8 violates the pumping lemma for regular languages, we can conclude that L8 is not regular.
No, the language L8 is not regular. A regular language can be recognized by a finite state automaton (FSA), which has a finite number of states and reads symbols from an input string to determine acceptance or rejection.
However, L8 violates the pumping lemma for regular languages, providing evidence that it is not regular.
The pumping lemma states that for any regular language L, there exists a pumping length p such that any string in L with a length of at least p can be divided into five parts: u, v, w, x, and y.
These parts satisfy three conditions: 1) vwx is the same as the original string, 2) v and x together have a length of at most p, and 3) for any natural number k, the string uv^kwx^ky is also in L.
In the case of L8, consider the string 0101101, where m = 3 and n = 2. According to the language definition, this string should be in L8. However, if we try to apply the pumping lemma, we run into a contradiction.
Since the string has a length of 7, which is less than p, we cannot divide it into five parts that satisfy the pumping lemma conditions.

Write a program that reads a list of words. Then, the program outputs those words and their frequencies The program should also delete duplicates and retain only one occurrence of each word, and keep its counts in a parallel int array. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words. Each word will always contain less than 10 characters and no spaces. See Sample Run below in the Criteria for Success section Hint Use two arrays, one char array for the strings and one int array for the frequencies. The output must have unique words and their occurrences before you deleted the duplicates. You may not use any temporary arrays to help you solve this problem.

Use only the concepts and functions we have learned so far. Here is a video that shows you how to read a list of words into a 2-dimensional char array Your program must have function prototypes. Place the prototypes for your functions globally, after your #includes. All functions must be implemented after main(). Try not to have any redundant code (repeated code) in your program. That is the purpose of functions.

Can Bob validate that the content of the message m has not been modified during transmission? Justify your answer. [3 marks)
i. Alice won't be able to send secret mail, because the private key is used to encrypt the message and without the private key she can't encrypt messages to ensure confidentiality.ii. Alice won't be able to decrypt the secret mail she receives because the public key is used for encryption and the private key is used for decryption. If she has lost her private key, Alice cannot decrypt any messages she receives.iii.
Alice can no longer sign the mail she sends because she needs the private key to create a digital signature. Digital signatures are used to ensure the integrity of a message. iv. Alice can verify the signature of the mail she receives because the public key is used to verify the signature of a digitally signed message. The digital signature provides authentication and integrity of the message.v. Bob can validate that the content of the message m has not been modified during transmission because Alice has encrypted the hash of the message using Bob's public key.
When Bob receives the message, he can use his private key to decrypt the hash and then compute the hash of the message himself. If the hash he computes matches the hash Alice sent, he can be sure that the message has not been modified during transmission. Therefore, the hash of a message can be used to ensure the integrity of a message.

Although there are specific rules for furniture placement that should generally be followed, sometimes you will need to bend the rules a little bit. When might it be acceptable to bend the rules for furniture spacing?
However, it might be acceptable to bend the rules for furniture spacing in certain situations such as:
1. Limited space: If you have a small room, you may need to move furniture closer together than recommended to make the most of the available space.
2. Personal preferences: If you prefer a certain arrangement that may not follow the standard rules, it is acceptable to adjust the spacing to suit your taste and style.
3. Unique room layout: Sometimes, the shape and layout of a room may require you to adjust the furniture spacing to fit the space properly.
4. Multifunctional spaces: If a room serves multiple purposes, such as a living room that also serves as a home office, you may need to modify the furniture placement to accommodate the different functions.
Regardless of the situation, it's crucial to ensure that the furniture arrangement still provides a comfortable and functional space.

(4) Which algorithm is suitable for this sequence 2 Describe the allocation process? (5)
(1)Draw allocation state when prog1, 2, 3 are loaded into memory? First-fit allocation algorithm should be used here. The memory allocation can be depicted as follows: The total size of the memory is 256KB. The operating system uses low address 20KB. Prog1 requests 80KB, prog2 requests 16KB, and Prog3 requests 140KB.
Prog1 uses the first 80KB of the memory. After this, 96KB of memory remains free, which is represented by the white space. Prog2 uses 16KB from the 96KB of free memory after Prog1, leaving 80KB of memory available. After this, Prog3 uses the first 96KB of the remaining memory, and the memory allocation state is as illustrated above. (2) Draw allocation state when prog1, 3 finish? When Prog1 and Prog3 are finished, the allocation state of memory is depicted below:
Prog1 uses 80KB from the first 96KB of memory allocated, and Prog3 uses the first 140KB of memory allocated. After both programs have completed, the allocated memory becomes free again. The memory size available is 80KB + 140KB = 220KB. The free memory can be allocated to other programs. (3) Use these two algorithms to draw the structure of the free queue after prog1, 3 finish. (draw the allocation descriptor information)Both the First-fit algorithm and Best-fit algorithm can be used to draw the structure of the free queue after Prog1, 3 finish.
First-Fit Algorithm: The allocation descriptor information is drawn as shown below: Best-fit Algorithm:(4) Which algorithm is suitable for this sequence 2 Describe the allocation process? Both the First-fit and Best-fit algorithms are suitable for this sequence. However, the best-fit algorithm is preferable because it optimizes the utilization of memory. First-fit Algorithm Allocation Process: Allocate memory to a program that first requests memory. The program must first receive the requested memory, and the memory must be allocated contiguously. If the required contiguous memory is not found, the allocation fails, and an error message is displayed. After that, the next program is considered. In this example, Prog1 is allocated first, then Prog2 and Prog3.Best-fit Algorithm Allocation Proces :Allocate the smallest possible block of memory from the available free memory. Prog1 is assigned to a 96KB block. When Prog2 is allocated, it searches the free memory for the smallest block of memory that is equal to or greater than the requested memory (16KB). The smallest available memory block is 80KB. Prog3 is allocated to the 140KB block. When Prog4 is allocated, it searches the free memory for the smallest block of memory that is equal to or greater than the requested memory (80KB). The smallest available memory block is 80KB. Then, Prog5 is assigned to the 120KB block.

Consider a computer system with the following configurations of Cache and main memory. The main memory has a total of 16 Mbytes (1 MByte = 2¹⁰ KBytes; 1 KByte = 2¹0 Bytes), where the basic addressable unit is 1 Byte. Assume that 1 word equals 1 Byte. The main memory has a block size of 32 Bytes. The Cache has a size of 128 KBytes. Q5.1 (3 pts) Assume direct mapping. Explain how the the address is divided into three fields: tag, line, word. That is, how many bits does each field contain, respectively? Q5.2 (2 pts) Assume associative mapping. Explain how the address is divided. Q5.3 (2 pts) Given an address 0001 1101 0011 1010 1011 1100, which line in cache is allocated to the block containing this Byte under direct mapping and associative mapping, respectively? Q 5.4 (3 pts) What's the main difference in terms of replacement policy between direct mapping and associative mapping?
The address in direct mapping is divided into three fields: the tag, line, and word.
The tag field contains the high-order bits, the line field contains the middle-order bits, and the word field contains the low-order bits.
The number of bits that each field contains is calculated using the formulas.
To compute the number of bits required for each field, we need to first find the number of bits needed to represent each field.
For Associative Mapping:
In associative mapping, the tag field of the address is compared to the tag fields of all lines in the cache.
If a match is found, then the corresponding line is used to access the block.
Since there is no explicit line number in the address, we cannot determine which line in the cache is allocated to the block containing this Byte. Instead, we have to search all lines in the cache to find a match for the tag.
If we find a match, then the corresponding line is used to access the block If another block with the same line number is loaded into the cache, the existing block is replaced.
In associative mapping, each block of main memory can be mapped to any line in the cache.

Which of the following is correct in terms of element movements required, when inserting a new element at the end of a List?
a. Array-List performs better than Linked-List.
b. Linked-List performs better than Array-List.
c. Linked List and Array-List basically perform the same.
d. All of the other answers
In terms of element movements required, Linked-List performs better than Array-List when inserting a new element at the end of a List.
Hence, option (b) is correct.
A Linked-List contains Nodes that have a reference to the next node in the List while an Array-List is a List implemented on top of a dynamically allocated array. While adding new items to an ArrayList, a new, larger array is frequently required as more objects are added, and the older array is copied to the new array after that, which is a resource-intensive process.
While, when we add a new element at the end of a Linked-List, we only need to modify the reference of the current last node to the new node, thus the amount of element movements required to insert a new element in a Linked-List is less than that in an Array-List. Hence, Linked-List performs better than Array-List in terms of element movements required when inserting a new element at the end of a List.

There are a few issues with the code. Here's the corrected version:
```javascript
const figure = document.getElementById("figure");
figure.addEventListener("change", (event) => {
if (!isNaN(parseFloat(figure.value))) {
class_limit = Math.ceil(parseFloat(event.target.value));
} else {
class_limit = event.target.value;
}
});
```
Here's an explanation of the corrections made:
1. The line `const figure = document.getElementById(figure");` has a syntax error. It should be `const figure = document.getElementById("figure");` with the closing double quote for the ID value.
2. The code was missing opening and closing curly braces for the arrow function inside the event listener. The corrected code is `(event) => { ... }`.
3. In the line `class_limit = Math.round(event.target.value)}`, there's a closing curly brace (`}`) after `value`. It should be removed to close the if statement properly.

Write a program Increasing Numbers that takes an integer input and computes the following formula: f(i) = {1 , i=1
{2 , i=2
{f(i-1)+f(i-2) , otherwise REQUIREMENTS • The user input is always correct (input verification is not required) • Your code must use recursion. • Your code must work exactly like the following example (the text in bold indicates the user input). Example of the program output: Example 1: Please input a positive integer: 15 The result of the formula for 15 is: 987 Example 2: Please input a positive integer: 12 The result of the formula for 12 is: 233
The program uses recursion to compute the value of the formula based on the given conditions and provides the output as shown in the examples.
Here's a Python program that satisfies the requirements and calculates the value of the formula using recursion:
def increasing_numbers(n):
if n == 1:
return 1
elif n == 2:
return 2
else:
return increasing_numbers(n - 1) + increasing_numbers(n - 2)
# Prompt the user for input
user_input = int(input("Please input a positive integer: "))
# Calculate the result using the formula
result = increasing_numbers(user_input)
# Display the result
print(f"The result of the formula for {user_input} is: {result}")
When you run this program, it will prompt you to enter a positive integer. After you input the number, it will calculate the value of the formula using recursion and display the result accordingly.
Example 1:
Please input a positive integer: 15
The result of the formula for 15 is: 987
Example 2:
Please input a positive integer: 12
The result of the formula for 12 is: 233
The program defines a recursive function called increasing_numbers that takes an integer n as input.If n is 1, the function returns 1. If n is 2, the function returns 2.For any other value of n, the function recursively calculates f(n-1) + f(n-2) by calling itself with n-1 and n-2 as arguments.The program prompts the user to enter a positive integer and reads the input.The program calls the increasing_numbers function with the user input as the argument and stores the result.Finally, the program prints the result using the formatted string that includes the user input.Learn more about program here:
