Explanation:
What will be the value of x after the following loop terminates?
int x = 10;
for (int i = 0; i < 3; i++)
x*= 1;
Answer:
10
Explanation:
This for-loop is simply iterating three times in which the value of x is being set to the value of x * 1. So let's perform these iterations:
x = 10
When i = 0
x = x * 1 ==> 10
When i = 1
x = x * 1 ==> 10
When i = 2
x = x * 1 ==> 10
And then the for-loop terminates, leaving the value of x as 10.
Hence, the value of x is equal to 10.

Explain the computer Memory and how it works
Brianna Watt, a consultant doing business as Watt Gives, wants a program to create an invoice for consulting services. Normally, she works on a project for five days before sending an invoice. She writes down the number of hours worked on each day and needs a program that asks for these amounts, totals them, and multiplies the amount by her standard rate of $30.00 per hour. The invoice should include Brianna’s business name, the client’s business name, the total number of hours worked, the rate, and the total amount billed. The information will be displayed onscreen. Using pseudocode, develope an algorithm to solve this program. Include standard documentation and comments.
Answer:
The pseudocode is as follows:
Total_Hours = 0
Input Client_Name
Rate = 30.00
For days = 1 to 5
Input Hours_worked
Total_Hours = Total_Hours + Hours_Worked
Charges = Rate * Total_Hours
Print "Brianna Watt"
Print Client_Name
Print Total_Hours
Print Rate
Print Charges
Explanation:
This initializes the total hours worked to 0
Total_Hours = 0
This gets input for the client name
Input Client_Name
This initializes the standard rate to 30.00
Rate = 30.00
This iterates through the 5 days of work
For days = 1 to 5
This gets input for the hours worked each day
Input Hours_worked
This calculates the total hours worked for the 5 days
Total_Hours = Total_Hours + Hours_Worked
This calculates the total charges
Charges = Rate * Total_Hours
This prints the company name
Print "Brianna Watt"
This prints the client name
Print Client_Name
This prints the total hours worked
Print Total_Hours
This prints the standard rate
Print Rate
This prints the total charges
Print Charges

Hi everyone,
I am having some troubles solving a python3 problem, maybe someone can help:
If we have the following array:
l = [10, 11, 0, 2]
By using map and filter function we should list:
["Even", "Odd", "Even", "Even"]
Thank you!
Answer:
Explanation:
You do not need the filter function to get that output, just the map function. You will however need a function that checks each element and returns Even or Odd if they are or not. The following code gives the output that you want as can be seen in the picture below.
def checkEven(s):
if s % 2 == 0:
return "Even"
else:
return "Odd"
l = [10, 11, 0, 2]
print(list(map(checkEven, l)))
Write a program that prompts the user for a word or phrase, and determines if the entry is a palindrome. A palindrome is a word or phrase which reads the same forwards and backwards. For example, if the user entered: madam the program should display: That is a palindrome Your program should ignore spaces, commas, and apostrophes, and ignore differences between upper and lower case. For example, the phrase: Madam, I'm Adam would be considered a palindrome.
Answer:
Explanation:
The following code is written in Python. It asks the user for an input. Then cleans the input using regex to remove all commas, whitespace, and apostrophes as well as making it all lowercase. Then it reverses the phrase and saves it to a variable called reverse. Finally, it compares the two versions of the phrase, if they are equal it prints out that it is a palindrome, otherwise it prints that it is not a palindrome. The test case output can be seen in the attached picture below.
import re
phrase = input("Enter word or phrase: ")
phrase = re.sub("[,'\s]", '', phrase).lower()
reverse = phrase[::-1]
if phrase == reverse:
print("This word/phrase is a palindrome")
else:
print("This word/phrase is NOT a palindrome")

Explanation:
Create a new Java project/class called ChangeUp. Create an empty int array of size 6. Create a method called populateArray that will pass an array, use random class to choose a random index and prompt the user to enter a value, store the value in the array. Note: Generate 6 random index numbers in an attempt to fill the array. Create a method called printArray that prints the contents of the array using the for each enhanced loop. Submit code. Note: It is possible that your array won't be filled and some values will still have 0 stored. That is acceptable.

//Initialize a counter variable to control the while loop
int i = 0;
//Begin the while loop. This loop runs as many times as the number of elements in the array - 6 in this case.
while(i < arr.length){
//generate random number using the Random object (rand) created above, and store in an int variable (randomNumber)
int randomNumber = rand.nextInt(6);
//(Optional) Print out a line for formatting purposes
System.out.println();
//prompt user to enter a value
System.out.println("Enter a value " + (i + 1));
//Receive the user input using the Scanner object(input) created earlier.
//Store input in an int variable (inputNumber)
int inputNumber = input.nextInt();
//Store the value entered by the user in the array at the index specified by the random number
arr[randomNumber] = inputNumber;
//increment the counter by 1

Explanation:
In the code provided, we are creating an array of size 6 to store integer values. The objective is to populate this array by taking input from the user for specific indexes chosen randomly.
To achieve this, we have defined two methods: populateArray and printArray.
The populateArray method takes an array as a parameter and fills it with values provided by the user. Here's how it works:
We create an instance of the Random class to generate random numbers and a Scanner object to read user input.We also create a boolean array called filledIndexes of the same size as the main array. This array will keep track of the indexes that have already been filled.Next, we use a loop to iterate six times (since we want to fill six elements in the array).Inside the loop, we generate a random index using random.nextInt(6). However, we want to make sure that we don't fill the same index twice. So, we check if the index is already filled by checking the corresponding value in the filledIndexes array.If the index is already filled (i.e., filledIndexes[index] is true), we generate a new random index until we find an unfilled one.Once we have a valid, unfilled index, we mark it as filled by setting filledIndexes[index] to true.We then prompt the user to enter a value for the chosen index and read the input using scanner.nextInt(). We store this value in the main array at the corresponding index.This process is repeated six times, ensuring that each index is filled with a unique value.The printArray method is responsible for printing the contents of the array. It uses a for-each enhanced loop to iterate over each element in the array and prints its value.
**By separating the population and printing logic into separate methods, the code becomes more modular and easier to understand.**

Book information (overriding member methods) Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a printlnfomethod that overrides the Book class printinfo() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes. Ex. If the input is The Hobbit J. R. R. Tolkien George Allen & Unwin 21 September 1937 The Illustrated Encyclopedia of the Universe James W. Guthrie Watson-Guptill 2001 2nd 1 the output is: Book Information: Book Title: The Hobbit Author: J. R. R. Tolkien Publisher: George Allen & Unwin Publication Date: 21 September 1937 Book Information: Book Title: The Illustrated Encyclopedia of the Universe Author: James W. Guthrie Publisher: Watson-Guptill Publication Date: 2001 Edition: 2nd Number of Volumes: 1 Note: Indentations use 3 spaces 261744 1399928 LAB ACTIVITY 11.17.1: LAB: Book information (overriding member methods) 0/10 File is marked as read only Current file: BookInformation.java 1 import java.util.Scanner; 3 public class BookInformation 2
Answer:
Explanation:
The Book class and BookInformation class was not provided but was found online. After analyzing both of these classes I have created the following code that grabs and overrides the printInfo() method in order to add and print the edition and number of volumes as well
public class Encyclopedia extends Book {
String edition;
int numVolumes;
public String getEdition() {
return edition;
}
public void setEdition(String edition) {
this.edition = edition;
}
public int getNumVolumes() {
return numVolumes;
}
public void setNumVolumes(int numVolumes) {
this.numVolumes = numVolumes;
}
public void printInfo() {
System.out.println("Book Information: ");
System.out.println(" Book Title: " + super.title);
System.out.println(" Author: " + author);
System.out.println(" Publisher: " + publisher);
System.out.println(" Publication Date: " + publicationDate);
System.out.println(" Edition: " + getEdition());
System.out.println(" Number of Volumes: " + getNumVolumes());
}

tegan works for an isp and has been asked to set up the ip addressing scheme for a new region of the city they are providing with internet service. she is provided the class b address of 141.27.0.0/16 as a starting point and needs at least 25 subnets. what is the custom subnet mask for this, how many networks does this allow for, and how many hosts will be available on each subnet
A custom subnet mask is also referred to as a variable-length subnet mask and it is used by a network device to identify and differentiate the bits (subnet ID) that is used for a network address from the bits (host ID) that is used for a host address on a network. Thus, it is typically used when subnetting or supernetting on a network.
Given the following data:
Class B address = 141.27.0.0/16Number of subnets = 25.Since the IP address is Class B, there are 16 bits for the subnet ID (141.27) while 16 are for the host ID. Thus, the custom subnet mask in dotted-decimal notation is equal to 255.255.0.0.
2. The custom subnet mask would allow for four (4) subnets.
3. There are 16 host bits available on each subnet.
