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.

use fruitful branching recursion
Part B: tree {#partB .collapse}
In this part, you will write a four-parameter function called tree that draws branching trees and returns the total length of all branches and leaves in the tree. These tree examples demonstrate how it should work.
In the tree, everything starts with a trunk (which might end up being the branch of a larger tree), and the first parameter of the tree function specifies the length of the trunk. The next parameter specifies the number of layers of branches and leaves above the trunk, in each layer the tree splits into two parts, drawn 40° left and 40° right of the angle of the trunk. These parts have trunk lengths which are 60% of the original trunk length, and each has one less layer below it.
The last two parameters specify the trunk/branch color and the leaf color respectively: all branches are drawn using the first color and all leaves are drawn using the second color. Whenever the number of layers is 0, a leaf is drawn instead of a trunk. A leaf is a line of the given trunk length where the pen size is set to 1/2 of that length. For all other parts of the tree, the pen size is set to 1/10 of the trunk length.
Note that the trunk draws in whatever direction the turtle is facing when the function starts, and the function must return the turtle to this starting position when it is done.
A few important restrictions:
tree must be recursive, and it must not use any loops. For full credit, it should have exactly two recursive calls.
You must call pencolor to set the pen color and call pensize to set the pen size within tree (the pen size is 1/10th of the trunk length, except for leaves where it is 1/2 of the length).
For the test file to work correctly, you must draw each branch & leaf only once (as opposed to drawing it forward and backwards, even if this would look the same). You must also draw the leaves after the branches they're connected to, so that the leaves are drawn on top of the branches
Define tree with 4 parameters
Use def to define tree with 4 parameters
Do not use any kind of loop

Within the definition of tree with 4 parameters, call pencolor or color in at least one place.
The `tree` function draws branching trees and returns the total length of all branches and leaves in the tree. Here is the definition of the `tree` function with four parameters:```python
import turtle
import math
def tree(trunk_length, num_layers, trunk_color, leaf_color):
t = turtle.Turtle()
if num_layers == 0:
t.pencolor(leaf_color)
t.pensize(trunk_length / 2)
t.forward(trunk_length)
length = trunk_length
else:
t.pencolor(trunk_color)
t.pensize(trunk_length / 10)
t.forward(trunk_length)
t.left(40)
length1 = tree(trunk_length * 0.6, num_layers - 1, trunk_color, leaf_color)
t.right(80)
length2 = tree(trunk_length * 0.6, num_layers - 1, trunk_color, leaf_color)
t.left(40)
length = length1 + length2 + trunk_length
t.penup()
t.backward(trunk_length)
t.pendown()
return length
```
In this function, the turtle moves forward and turns at a 40 degree angle to create the branching effect of the tree. The function stops when the `num_layers` variable is 0, at which point it draws a leaf instead of a trunk. The function uses recursion to call itself to draw smaller branches until it reaches the leaf.In the function, we've also used the `pencolor` and `pensize` methods to set the color and thickness of the pen. The `penup` and `pendown` methods are also used to move the pen without drawing lines and to start drawing lines again when necessary. Finally, the function returns the total length of all branches and leaves in the tree.

1.1
List and describe the properties that all database transactions should display
1.2
Briefly discuss the techniques used in transaction recovery procedures.
1.1 Properties that all database transactions should display: Atomicity: A transaction's atomicity assures that it is all or nothing. Consistency: The database's integrity constraints must be satisfied for the transaction to commit. Isolation: A transaction's modifications should not be visible to other transactions until it has been committed.
Durability: The transaction's committed modifications should persist even in the case of a system failure.1.2 Techniques used in transaction recovery procedures: Shadow paging: Shadow paging involves having a shadow copy of the database. It comprises a dirty bit for each page, which indicates if it has been altered during the transaction.
Checkpoints: At intervals, a system can make checkpoints. The log is copied to stable storage and flushed to disk during a checkpoint. In the event of a crash, the database can be restored to the most recent checkpoint, and transactions may be re-applied from the log after the checkpoint.

Write a loop that generates the following output (exactly as seen):
01, 02: 03, 04: 05, 06; 07, 08: 09, 10: 11, 12; 13, 14: 15.
16: 17, 18; 19, 20: 21, 22: 23, 24; 25, 26: 27, 28: 29, 30.
Except for the leading zeros, numbers are not allowed to be hard coded (use the loop's counter!). A selection statement must be used to determine what punctuation marks to output. Hint: modulo
You may not test for specific numbers when determining punctuation. For example, the following method is not allowed:
if(x == 17 || x == 19 || x == 21)
cout << ",";
The algorithm must be written in a separate function, not in main ().
Here's the solution for the given problem that generates the following output using the loop in C++:01, 02: 03, 04: 05, 06; 07, 08: 09, 10: 11, 12; 13, 14: 15.16: 17, 18; 19, 20: 21, 22: 23, 24; 25, 26: 27, 28: 29, 30. We will use the modulo operator to place the appropriate punctuation. Given below is the C++ code to achieve the same :
#include
using namespace std;
void printNum(int n){
if (n < 10){
cout << "0" << n;
} else{
cout << n;
}
}
void generateOutput(){
for (int i = 1; i <= 30; i++){
printNum(i);
if (i % 30 == 0){
cout << "." << endl;
} else if (i % 6 == 0){
cout << "; ";
} else if (i % 2 == 0){
cout << ", ";
} else{
cout << ": ";
}
}
}
int main(){
generateOutput();
return 0;
}
In the code above, we are using the modulo operator to determine the punctuation to place between the numbers. The printNum () function is used to print the numbers with leading zeros when needed. The generate Output () function contains the loop that iterates through the numbers from 1 to 30 and places the appropriate punctuation between the numbers.

Using the CelsiusTokelvin function as a guide, create a new function, changing the name to Kelvin ToCelsius, and modifying the function accordingly
To add two more statements to the main() function to test inputs 3 and 1, and to create a new function called KelvinToCelsius, you can modify the code as follows:
```csharp
using System;
class Program
{
static double CelsiusToKelvin(double celsius)
{
double kelvin = celsius + 273.15;
return kelvin;
}
static double KelvinToCelsius(double kelvin)

double celsius = kelvin - 273.15;
return celsius;
}
static void Main(string[] args)
{
double temperature = 25.0;
double convertedTemperature = CelsiusToKelvin(temperature);
Console.WriteLine("Temperature in Kelvin: " + convertedTemperature);
temperature = 3.0;
convertedTemperature = CelsiusToKelvin(temperature);
Console.WriteLine("Temperature in Kelvin: " + convertedTemperature);
temperature = 1.0;
convertedTemperature = CelsiusToKelvin(temperature);
Console.WriteLine("Temperature in Kelvin: " + convertedTemperature);
double kelvinTemperature = 298.15;
double celsiusTemperature = KelvinToCelsius(kelvinTemperature);
Console.WriteLine("Temperature in Celsius: " + celsiusTemperature);
}
}
```
In the modified code, two additional statements have been added to the main() function to test inputs 3 and 1.
The CelsiusToKelvin() function is called with the respective temperature values, and the converted temperatures in Kelvin are printed using Console.WriteLine().
Additionally, a new function called KelvinToCelsius() has been added, which takes a temperature value in Kelvin as input and converts it to Celsius.
The function follows a similar logic as the CelsiusToKelvin() function but performs the inverse conversion. The result is stored in the variable celsius temperature and printed using Console.WriteLine().

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.

[Cybercrime in South Africa]
South African residents are at a high risk of having their personal details exploited by malicious actors, according to research from Surfshark.
The study ranked South Africa sixth in the world when it comes to the nations most threatened by cybercrime, but its numbers are relatively low compared to the UK and the US. The methodology behind the study included assigning figures for cyber threats, financial losses, and probability points to determine how likely residents of a country are to have their exposed data accessed and used maliciously.
Surfshark said it used FBI data to develop its index.
It lists South Africa seventh in terms of the number of cybercrime victims — behind France.
Transnet ransomware attack
Transnet was the victim of a cyberattack that forced the company to declare force majeure at container terminals and adjust to the manual processing of cargo.
South Africa’s port and rail company appeared to have been hit by a similar strain of ransomware linked to a chain of high-profile data breaches likely carried out by cybercriminals from Eastern Europe and Russia.
A ransom note left by the attackers claimed they had encrypted Transnet’s files, including a terabyte of personal data, financial reports and other documents.
As with many ransomware attacks, it also directed Transnet to a dark web chat portal to negotiate with the hackers. Public enterprises minister Pravin Gordhan later revealed that no ransom had been paid during a media update in August 2021.
TransUnion confirmed that the data included ID numbers, date of birth, gender, telephone number, email address, physical address, marital status, employer, duration of employment, vehicle finance contract number, and vehicle identification number.
N4ughtySecTU — the group that claimed responsibility for the attack — alleged it had acquired 4TB of data that included a database of 54 million South Africans. TransUnion received a ransom demand of $15 million (R237 million), which it refused to pay.
Although TransUnion claims the attacker exfiltrated 3.6 million records from its systems, N4ughtySecTU said it obtained several databases.
These include an ANC member database, a Cell C customer database, and TransUnion’s own customer database for its identity protection product.
2.1 Assuming you have been invited as a security analyst, tasked with analysing the data breach and advising Transnet on the security systems they should put in place to prevent the data breaches from happening again.
a. Write a comprehensive report to the Chief Information Officer advising him on the policies, tools and security systems that Transnet should put in place to prevent another breach from happening.

2.2 The increase in cybercrime has not only affected big companies alone. Civilian have continued to fall prey to cybercriminals daily. How can individual South African protect themselves against cyber-crime?
2.1 Report to the Chief Information Officer advising on the policies, tools and security systems that Transnet should put in place to prevent another breach from happening:As a security analyst, the following policies, tools and security systems need to be put in place to prevent another data breach in Transnet:1. Implement Access Control Measures: Transnet must implement access control measures to regulate the flow of people entering their premises. Physical access controls such as smart cards, biometric systems, and cameras should be put in place to monitor who comes in and out of the premises.
The company should also restrict access to sensitive information and ensure employees have access to only the information they need to perform their duties.2. Firewall Implementation: Transnet needs to have firewalls in place to block unauthorized access to their servers and prevent unauthorized individuals from accessing their systems. Firewalls can also be used to prevent malware and other malicious software from entering the company's network.3. Data Encryption: Data encryption can help to prevent unauthorized access to sensitive information in the event of a data breach. Encryption tools should be put in place to encrypt sensitive information such as financial reports and personal data.
4. Regular System Updates and Backups: Transnet should have a policy in place that ensures that all systems are up to date and all security patches are installed to prevent vulnerabilities. In addition, regular data backups should be performed in the event of a data breach or system failure.5. Employee Training: Employees should be trained on the best practices to keep the company's data secure. This includes password management, identifying phishing attacks and other types of cyber threats.6. Incident Response Plan: Transnet should develop an incident response plan that outlines the steps to be taken in the event of a cyber attack. The plan should include who to contact, what steps to take, and how to mitigate the damage.

\( \mathcal{H} \)-Given the language: \[ L_{8}=\left\{0^{m}(101)^{n} \mid m, n \in \mathbb{Z} \text { and } m, n \geq 1 \text { and } m \geq n\right\} \] Is \( L_{8} \) Regular? Circle the appropriate
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.

which of the following are ways in which tcp detects congestion? (check all that apply) group of answer choices the destination host sends an icmp message to the sender when the network is congested. congestion is inferred when there are too many timeouts on sent packets. congestion can be detected only after congestion collapse has occurred. tcp monitors the network utilization, and infers congestion when utilization exceeds 80%.
The ways in which TCP detects congestion are: Congestion is inferred when there are too many timeouts on sent packets: When packets are lost or not acknowledged within a certain timeout period, it is an indication of network congestion.
TCP interprets these timeouts as a sign of congestion and adjusts its congestion control mechanism accordingly.
TCP monitors the network utilization and infers congestion when utilization exceeds 80%: TCP keeps track of the network's available bandwidth and compares it with the current utilization. If the utilization exceeds a certain threshold, typically around 80%, TCP assumes that congestion is occurring and reacts by reducing its sending rate.
So the correct options are: Congestion is inferred when there are too many timeouts on sent packets.
TCP monitors the network utilization and infers congestion when utilization exceeds 80%.

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 multiple ways of rewriting the given function while still having the same logic. One of the ways is shown below:void run_first_course(FILE *ofp, failfish_queue **ponds) {fprintf(ofp, "\nFirst Course\n");
int i = 0;while(i < 10 && ponds[i] == NULL) i++;if(i < 10) {fprintf(ofp, "\nPond %d: %s\n", i + 1, ponds[i]->pondname);first_course(ofp, ponds[i]);}} In the given function, the for loop is used to iterate through an array of 10 elements. Then the if statement checks if the current element is not NULL and if it is not, then the function first_course() is called.
If the current element is NULL, then the for loop continues with the next iteration.In the rewritten function, the for loop is replaced with a while loop. The while loop first checks if the index is less than 10 and the element at that index is NULL. If the element is NULL, then the index is incremented by 1. This continues until a non-NULL element is found or the index becomes 10. Then, if a non-NULL element is found, the function first_course() is called on that element and the loop ends. Otherwise, the loop ends without calling the function. Hence, the logic remains the same but the structure of the loop is different.

A C-style string is a character array with a special character '\0' indicating the end (therefore its length need not be passed around as with other arrays). Here's an example: char cstr [6] = {'h', 'e','1','1', 'o', '\0'};' Assume the characters are ASCII encoded. Write a function which produces a new dynamically allocated C-string which is the same length as the input, however all of the lowercase characters a, b, ..., z are replaced with their uppercase equivalent. Its exact signature should be: char* to upper (char* original); The function should not modify characters outside the lowercase range. The only built-in function you may use is strlen(). Do not use std::string.
The statement "The character with the ASCII code 0 is called the NUL character" is true. In C and C++, the NUL character, represented by '\0', is used as a sentinel value to indicate the end of a C-string. It is used to mark the termination of character sequences and is not considered a printable character.
- C-strings are character arrays that rely on the NUL character ('\0') to determine the end of the string.
- The NUL character has an ASCII code of 0, and its presence at the end of a C-string allows various string functions to identify the end of the string.
- By convention, C-strings are terminated with the NUL character to ensure proper string handling and prevent reading beyond the intended string length.
- The NUL character is not considered part of the visible characters in the string but rather serves as a termination marker.
- Understanding the NUL character and its role in C-strings is crucial for correctly working with C-string functions and ensuring proper string manipulation and termination.

The function should take two arguments. • item: a string to search for in the second parameter • collection : either a list or a tuple The function should return a boolean denoting whether or not the item can be found within the collection. If either parameter is the wrong type, your function should return None.
The code implementation for the function called `contains` is shown below: def contains(item, collection).
The function takes two parameters, `item` and `collection`. The function checks the type of the `collection` parameter to ensure that it is either a `list` or `tuple`, and the `item` parameter is of type `str`.The `contains` function returns a `boolean` indicating whether or not the `item` can be found within the `collection`.
It does this by checking if `item` is present in `collection`. If `item` is present in `collection`, it returns `True`; otherwise, it returns `False`.In the event that either parameter is of the wrong type, the function returns `None`.

Write a Python program that returns (by printing to the screen) the price, delta and vega of European and American options using a binomial tree. Specifically, the program should contain three functio
To write a Python program that calculates the price, delta, and vega of European and American options using a binomial tree, you can create three functions:
1. `binomial_tree`: This function generates the binomial tree by taking inputs such as the number of steps, the time period, the risk-free rate, and the volatility. It returns the tree structure.
2. `option_price`: This function calculates the option price using the binomial tree generated in the previous step. It takes inputs such as the strike price, the option type (European or American), and the tree structure. It returns the option price.
3. `option_greeks`: This function calculates the delta and vega of the option using the binomial tree and option price calculated in the previous steps. It returns the delta and vega.
Here is an example implementation of these functions:
```
def binomial_tree(steps, time_period, risk_free_rate, volatility):
# Generate the binomial tree using the inputs
# Return the tree structure
def option_price(strike_price, option_type, tree_structure):
# Calculate the option price based on the strike price, option type, and tree structure
# Return the option price
def option_greeks(tree_structure, option_price):
# Calculate the delta and vega of the option based on the tree structure and option price
# Return the delta and vega
# Example usage:
tree = binomial_tree(100, 1, 0.05, 0.2)
price = option_price(50, "European", tree)
delta, vega = option_greeks(tree, price)
# Print the results
print("Option Price:", price)
print("Delta:", delta)
print("Vega:", vega)
```
In this example, the `binomial_tree` function generates a tree with 100 steps, a time period of 1 year, a risk-free rate of 5%, and a volatility of 20%. The `option_price` function calculates the option price for a European option with a strike price of 50. Finally, the `option_greeks` function calculates the delta and vega based on the tree structure and option price. The results are then printed to the screen.
