Answer:
# Get the input from the user
userText = input()
fourthChar = input()
# Replace the fourth character of the string with the new character
userText = userText[:3] + fourthChar + userText[4:]
# Print the modified string
print(userText)
Explanation:
This code first gets the input from the user and stores it in the userText and fourthChar variables. It then uses string slicing to replace the fourth character of the string with the new character. Finally, it prints the modified string.
The input string is cheetah, and the fourth character is e. The code replaces this character with the new character v, resulting in the modified string chevtah.

Write a function named replaceSubstring. The function should accept three string object arguments entered by the user. We want to look at the first string, and every time we say the second string, we want to replace it with the third. For example, suppose the three arguments have the following values: 1: "the dog jumped over the fence" 2: "the" 3: "that" With these three arguments, the function would return a string object with the value "that dog jumped over that fence". Demonstrate the function in a complete program. That means you have to write the main that uses this.
Answer:
public class Main{
public static void main(String[] args) {
System.out.println(replaceSubstring("the dog jumped over the fence", "the", "that"));
}
public static String replaceSubstring(String s1, String s2, String s3){
return s1.replace(s2, s3);
}
}
Explanation:
*The code is in Java.
Create function called replaceSubstring that takes three parameters s1, s2, and s3
Use the replace function to replace the s2 with s3 in s1, then return the new string
In the main:
Call the replaceSubstring function with the given strings and print the result

Python programming using def function
Give the user a math quiz where they have
to subtract 2-digit integers. Present them
like this: 67 - 55.
Each time, tell the user whether they are
correct or incorrect. Continue presenting
problems to them until they enter a zero to
quit. At the end print the number right,
the number wrong, and the percent right.
Explanation:
For this program we'll need to know a couple concepts which are: while loops, user input, variables, converting strings to integers, and basic arithmetic operators, if statements, and the random module.
So let's first just declare the basic function, we can call this "main", or something a bit more descriptive, but for now I'll name it "main".
def main():
# code will go here
main()
so now from here, we want to initialize some variables. We need to somehow keep track of how many they get correct and how many they've answered.
These two numbers may be the same, but at times they will be different from each other, so we'll need two variables. Let's just call the variable tracking how much have been answered as "answered" and the variable tracking how much are correct as "correct".
These two will initially be zero, since the user hasn't answered any questions or gotten any correct. So now we have the following code
def main():
correct = 0
answered = 0
main()
Now let's use a while loop, which we break out of, once the user inputs zero. This may be a bit tricky if we use a condition since we'll have to ask for input before, so let's just use a while True loop, and then use an if statement to break out of it at the end of the loop.
Now we want to generate two numbers so we can use the random module. To access the functions from the random module you use the import statement which will look like this "import random". Now that you have access to these functions, we can use the randint function which generates random numbers between the two parameters you give it (including those end points). It says two digits, so let's use the endpoints 10 and 98, and I'll explain later why I'm limiting it to 98 and not 99.
The reason we want to limit it to 98 and not 99, is because it's possible for the two randomly generated numbers to be equal to each other, so the answer would be zero. This is a problem because the zero is used to quit the program. So what we can do in this case, is add one to one of the numbers, so they're no longer equal, but if they're equal to 99, then now we have a three digit number.
Now onto the user input for simplicitly, let's assume they enter valid input, all we have to do is store that input in a variable and convert it into an integer. We can immediately convert the input into an integer by surrounding the input by the int to convert it.
we of course want to display them the equation, and we can either do this through string concatenation or f-strings, but f-strings are a bit more easier to read.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2:
num2 += 1
userInput = int(input(f"{num1} - {num2}"))
main()
from here we first need to check if they entered zero and if so, break out of the loop. If they didn't enter zero, check if the userInput is equal to the actual answer and if it is, then add one to correct and finally add one to answered regardless of whether their answer is correct or not.
Outside the loop to display how much they got correct we can use an f-string just like we did previously. Since sometimes we'll get a non-terminating decimal, we can use the round function so it rounds to the nearest hundreth.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2: # the answer would be zero
num2 += 1 # makes sure the answer isn't zero
userInput = int(input(f"{num1} - {num2}"))
if userInput == 0: # first check if they want to stop
break
if userInput == (num1 - num2):
correct += 1
answered += 1
print(f"Correct: {correct}\nIncorrect: {answered - correct}\nPercent: {round(correct/answered, 2)}")
main()
and that should pretty much be it. The last line is just some formatting so it looks a bit better when displaying.

Write a function addUpSquaresAndCubes that adds up the squares and adds up the cubes of integers from 1 to N, where N is entered by the user. This function should return two values - the sum of the squares and the sum of the cubes. Use just one loop that generates the integers and accumulates the sum of squares and the sum of cubes. Then, write two separate functions sumOfSquares and sumOfCubes to calculate and return the sums of the squares and sum of the cubes using the explicit formula below.
Answer:
All functions were written in python
addUpSquaresAndCubes Function
def addUpSquaresAndCubes(N):
squares = 0
cubes = 0
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
return(squares, cubes)
sumOfSquares Function
def sumOfSquares(N):
squares = 0
for i in range(1, N+1):
squares = squares + i**2
return squares
sumOfCubes Function
def sumOfCubes(N):
cubes = 0
for i in range(1, N+1):
cubes = cubes + i**3
return cubes
Explanation:
Explaining the addUpSquaresAndCubes Function
This line defines the function
def addUpSquaresAndCubes(N):
The next two lines initializes squares and cubes to 0
squares = 0
cubes = 0
The following iteration adds up the squares and cubes from 1 to user input
for i in range(1, N+1):
squares = squares + i**2
cubes = cubes + i**3
This line returns the calculated squares and cubes
return(squares, cubes)
The functions sumOfSquares and sumOfCubes are extract of the addUpSquaresAndCubes.

Answer:
c. Sponge
Explanation:
Sponge is the function in cryptography takes a string of any length as input and returns a string of any requested variable length. Hence, option C is correct.
What is Sponge is the function in cryptography?Any of a class of algorithms with finite internal state that accept an input bit stream of any length and produce an output bit stream of any desired length is referred to as a sponge function or sponge construction in the field of cryptography. There are theoretical and practical applications for sponge functions.
A generalisation of both stream cyphers with a fixed input length and hash functions, which have a fixed output length, is a sponge function. It works by repeatedly applying the inner permutation on a finite state while also entering input or retrieving output.
Data can be "absorbed" into the sponge that SHA-3 is built like and then "squeezed" out again. A subset of message blocks is XORed during the absorption phase.
Thus, option C is correct.

Can someone help me with the following logical circuit, perform two actions. FIRST, convert the circuit into a logical
statement. SECOND, create a truth table based on the circuit/statement. (20 pts. each for statement and
truth table.
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.
Given the logical circuit, we are required to perform two actions on it. Firstly, convert the circuit into a logical statement. Secondly, create a truth table based on the circuit/statement. Let's understand how to do these actions one by one:Conversion of Circuit into Logical Statement.
The given circuit contains three components: NOT gate, AND gate and OR gate. Let's analyze the working of this circuit. The two input variables A and B are first passed through the NOT gate, which gives the opposite of the input signal.
Then the NOT gate output is passed through the AND gate along with the input variable B. The output of the AND gate is then passed through the OR gate along with the input variable A.We can create a logical statement based on this working as: (not A) and B or A. This can also be represented as A or (not A) and B. Either of these statements is correct and can be used to construct the truth table.
Creation of Truth Table Based on the logical statement, we can create a truth table as shown below:
A B (not A) (not A) and B (not A) and B or A A or (not A) and B 0 0 1 0 1 0 0 1 0 0 1 0 1 1 0 1 1 0 1 1 1 0 1 1 0 1 1 0 1 1 1
In the truth table, we have all possible combinations of input variables A and B and their corresponding outputs for each component of the circuit.
The first two columns show the input values, the next column shows the output of the NOT gate, then the output of the AND gate, then the output of the OR gate and finally the output of the logical statement.
We can observe that the output of the logical statement is the same as the output of the OR gate.

At that time, the battery is receiving all of the circuit's voltage (by the path of least resistance), and no voltage is passing through the metre (0 volt reading).
Thus, the correct option is C.
