Explanation:
The program is well explained in the comments attache with each line of program. The program has three methods. One is the main method to start the game and prompts user to enter a choice and converts the user input choice to upper case. One is CompChoice method that generates three random numbers and uses switch statement to set 1 for Rock, 2 for Paper and 3 for Scissors . One method is results that takes computer choice and player choice as parameters to decide the winner. It uses if else statements to check if choice of user wins from choice of computer or vice versa. It uses a boolean variable youWin which is set to true when player choice beats computer choice otherwise is set to false. At the end if youWin is true then the player is declared winner otherwise not. The screenshot of the program output is attached.

Write a method called min that takes three integers as parameters and returns the smallest of the three values, such that a call of min(3, -2, 7) would return -2, and a call of min(19, 27, 6) would return 6. Use Math.min to write your solution.
Answer:
public class Main
{
public static void main(String[] args) {
System.out.println(min(3, -2, 7));
}
public static int min(int n1, int n2, int n3){
int smallest = Math.min(Math.min(n1, n2), n3);
return smallest;
}
}
Explanation:
*The code is in Java.
Create a method named min that takes three parameters, n1, n2, and n3
Inside the method:
Call the method Math.min() to find the smallest among n1 and n2. Then, pass the result of this method to Math.min() again with n3 to find the min among three of them and return it. Note that Math.min() returns the smallest number among two parameters.
In the main:
Call the method with parameters given in the example and print the result
Methods are named program statements that are executed when called/invoked.
The method in Python, where comments are used to explain each line is as follows:
#This defines the method
def mmin(a,b,c):
#This calculates the smallest of the three values using math.min
minNum = min(a,b,c)
#This prints the smallest value
return minNum

Which of the following is true about strings?
They cannot be stored to a variable
An input (unless otherwise specified) will be stored as a string
They do not let the user type in letters, numbers and words
They are used for arithmetic calculations
Answer:
Your answer is option C, or the third option.
They do not let the user type in letters, numbers, and words.
Explanation:
Strings are defined as a sequence of characters literal, constant, or variable. These sequences are like an array of data or list of code that represents a structure. Formally in a language, this includes a finite(limited) set of symbols derived from an alphabet. These characters are generallu given a maximum of one byte of data each character. In longer languages like japanese, chinese, or korean, they exceed the 256 character limit of an 8 bit byte per character encoding because of the complexity of the logogram(character representing a morpheme((which is the simpliest morphological(form or structure) unit of language with meaning)) character with 8 bit (1 byte, these are units of data) refers to cpu(central processing unit) which is the main part of a computer that processes instructions, and sends signals.
CJ is developing a new website blogging about cutting-edge technologies for people with special needs. He wants to make the site accessible and user friendly.
CJ knows that some of the visitors who frequent his website will use screen readers. To allow these users to bypass the navigation, he will use a skip link, He wants to position the skip link on the right but first he must use the ____ property.
a) display
b) right
c) left
d) nav
Answer:
The answer is "Option c".
Explanation:
It is an internal page reference which, whilst also completely new pages, allow navigating around the current page. They are largely used only for bypassing and 'skipping' across redundant web page content by voice command users, that's why the CJ would use a skip link to enable those users to bypass specific navigation, and he also wants to put this link on the right, but first, he needs to use the left property.
Define a function called sum, for a given an array and an int representing its size, if the size is at least 3, then sum up all elements whose indices are a multiple of 3 and return that value, otherwise, return 0.
Answer:
Written in C++
int sum(int arr[], int size) {
int total = 0;
if(size>=3) {
for (int i = 0; i < size; ++i) {
if(i%3 == 0) {
total += arr[i];
}
}
}
return total;
}
Explanation:
This line defines the function
int sum(int arr[], int size) {
This line initializes sum to 0
int total = 0;
This line checks if size is at least 3
if(size>=3) {
This loop iterates through the array
for (int i = 0; i < size; ++i) {
The following adds multiples of 3
if(i%3 == 0) {
total += arr[i];
}
}
}
This returns the calculated sum
return total;
}

Is 583 a string or a number?
Answer:
a string
answer
You are given an array of integers, each with an unknown number of digits. You are also told the total number of digits of all the integers in the array is n. Provide an algorithm that will sort the array in O(n) time no matter how the digits are distributed among the elements in the array. (e.g. there might be one element with n digits, or n/2 elements with 2 digits, or the elements might be of all different lengths, etc. Be sure to justify in detail the run time of your algorithm.
Answer:
Explanation:
Since all of the items in the array would be integers sorting them would not be a problem regardless of the difference in integers. O(n) time would be impossible unless the array is already sorted, otherwise, the best runtime we can hope for would be such a method like the one below with a runtime of O(n^2)
static void sortingMethod(int arr[], int n)
{
int x, y, temp;
boolean swapped;
for (x = 0; x < n - 1; x++)
{
swapped = false;
for (y = 0; y < n - x - 1; y++)
{
if (arr[y] > arr[y + 1])
{
temp = arr[y];
arr[y] = arr[y + 1];
arr[y + 1] = temp;
swapped = true;
}
}
if (swapped == false)
break;

To create a public key signature, you would use the ______ key.
Answer:
To create a public key signature, you would use the _private_ key.
Explanation:
To create a public key signature, a private key is essential to enable authorization.
A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.
The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.
The public key uses different keys to make data readable and unreadable.
The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.

Answer:
Follows are the method definition to this question:
void Reverse_Order(struct Node* h)//defining a recursive method Reverse_Order that takes structure in parameter
{
if (h == NULL)//use if block to check head equal to null
return;//use return keyword
Reverse_Order(h->next);//call method recursively
cout<<h->data;//print data
}
Explanation:
In the above code, a recursive method "Reverse_Order" takes structure as the parameter, and inside the method, structure variable h is used that uses the if conditional statement to check the header equal to null.
In the condition is true, it will use the return keyword, and in the next step, it calls the method recursively, and print its value in the reverse order.

Write a program that takes as input a number of kilometers and prints the corresponding number of nautical miles.
Use the following approximations:
A kilometer represents 1/10,000 of the distance between the North Pole and the equator.
There are 90 degrees, containing 60 minutes of arc each, between the North Pole and the equator.
A nautical mile is 1 minute of an arc.
An example of the program input and output is shown below:
Enter the number of kilometers: 100
The number of nautical miles is 54
In python:
kilos = int(input("Enter the number of kilometers: "))
print(f"The number of nautical miles is {round(kilos/1.852,2)}")
I hope this helps!
For an input of 100 kilometers, the program displays "The number of nautical miles is 54.00."
To convert kilometers to nautical miles based on the given approximations.
Here are the simple steps to write the code:
1. Define a function called km_to_nautical_miles that takes the number of kilometers as input.
2. Multiply the number of kilometers by the conversion factor [tex](90 / (10000 \times 60))[/tex] to get the equivalent number of nautical miles.
3. Return the calculated value of nautical miles from the function.
4. Prompt the user to enter the number of kilometers they want to convert.
5. Read the user's input and store it in a variable called kilometers.
6. Call the km_to_nautical_miles function, passing the kilometers variable as an argument, to perform the conversion.
7. Store the calculated value of nautical miles in a variable called nautical_miles.
8. Display the result to the user using the print function, formatting the output string as desired.
Now the codes are:
def km_to_nautical_miles(km):
nautical_miles = (km * 90) / (10000 * 60)
return nautical_miles
kilometers = float(input("Enter the number of kilometers: "))
nautical_miles = km_to_nautical_miles(kilometers)
print(f"The number of nautical miles is {nautical_miles:.2f}.")
The output of this program is:
The result is displayed to the user as "The number of nautical miles is 54.00."
