Answer:
Here is the corrected code:
import java.util.*;
public class DebugNine36 { //class name
public static void main(String[] args) { //start of main method
ArrayList<String>products = new ArrayList<String>(); //creates an ArrayList of type String names products
products.add("shampoo"); //add shampoo to product array list
products.add("moisturizer"); //add moisturizer product array list
products.add("conditioner"); //add conditioner product array list
Collections.sort(products); //sort the elements in products array list
display(products); //calls display method by passing products array list
final String QUIT = "quit"; //declares a variable to quit the program
String entry; //declares a variable to hold product/element or quit
Scanner input = new Scanner(System.in); //creates Scanner object
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //prompts user to enter a product or enter quit to exit
entry = input.nextLine(); //reads the entry value from user
while(!entry.equals("quit")) { //loops until user enters quit
products.add(entry); //adds entry (product) to products array list
Collections.sort(products); //sorts the elements in products array list
display(products); //calls display method by passing products arraylist
System.out.print("\nEnter a product or " + QUIT + " to quit >> "); //keeps prompting user to enter a product or enter quit to exit
entry = input.nextLine(); } } //reads the entry value from user
public static void display(ArrayList products) { // method to display the list of products
System.out.println("\nThe size of the list is " + products.size()); //displays the size of the array list named products
for(int x = 0; x < products.size(); ++x) //iterates through the arraylist products
System.out.println(products.get(x)); } } //displays each item/element in products array list
Explanation:
In the code the following statement are corrected:
1.
ArrayListproducts = new ArrayList();
This gave an error: cannot find symbol
This is corrected to :
ArrayList<String>products = new ArrayList<String>();
2.
products.add(shampoo);
products.add(moisturizer);
products.add(conditioner);
Here shampoo moisturizer and conditioner are String type items that are to be added to the products so these strings have to be enclosed in quotation marks.
This is corrected to :
products.add("shampoo");
products.add("moisturizer");
products.add("conditioner");
3.
display();
This method is called without giving any arguments to this method. The method display takes an ArrayList as argument so it should be passed the arraylist products to avoid error that actual and formal argument lists differ in length .
This is corrected to :
display(products);
The screenshot of output is attached.

Write a C program that creates a function bitFlip() that takes an int parameter and returns an int that has all of the int that was passed in bits flipped.
It changes all 0s to 1s and all 1s to 0s. In the main function, read in an int num using scanf, call bitFlip(), and the function returns num with its bits flipped.
Output example:
Enter an integer: 2
Integer before bits were flipped: 00000000000000000000000000000010
Integer after bits were flipped: 11111111111111111111111111111101
The flipped number is: -3
Answers
Answer:
Here's an example C program that implements the bitFlip() function:
#include <stdio.h>
int bitFlip(int num) {
return ~num; // Use bitwise NOT operator to flip all bits
}
int main() {
int num;
printf("Enter an integer: ");
scanf("%d", &num);
printf("Integer before bits were flipped: %032d\n", num); // Use %032d to print leading zeros
num = bitFlip(num);
printf("Integer after bits were flipped: %032d\n", num);
printf("The flipped number is: %d\n", num);
return 0;
}
The bitFlip() function takes an int parameter num and returns an int with all of its bits flipped using the bitwise NOT operator ~.
In the main() function, we first read in an integer num using scanf(). We then print out the binary representation of num using the %032d format specifier to ensure that it has 32 bits with leading zeros. We then call bitFlip() to flip the bits of num and print out the binary representation of the flipped number. Finally, we print out the value of the flipped number using %d.
Sample output:
Enter an integer: 2
Integer before bits were flipped: 00000000000000000000000000000010
Integer after bits were flipped: 11111111111111111111111111111101
The flipped number is: -3

8. To be a Bunk Leader, a staff member must have over 4 service years and have completed leadership training. In cell L2, enter a formula using the IF and AND functions, as well as structured references to determine if Adam Moriarty can be a bunk leader. a. The logical test in the IF function should determine if the staff member’s Service Years is greater than 4 AND the staff member’s Leadership Training status is "Yes". Remember to use a structured reference to the Service Years and the Leadership Training columns. b. The function should return the text Yes if a staff member meets both of those criteria.
Answers
Answer:
=IF(AND([Service Year]>4,[Leadership Training]="Yes"),"Yes","No")
Explanation:
To make use of structured references, a table has to be defined (created). Assume that the table definition is as follows;
Staff --- Service Year --- Leadership Training --- Status
In cell L2, type the above formula
Analyzing the formula:
=; An Excel formula must start with an = sign
IF; This signifies that the formula is an "IF" function
AND; This signifies that there are more than one condition in thee formula and all conditions must be true
[Service Year]>4; The question requires that the formula uses a structured referencing. Structured referencing is such that the columns of a table are called instead of cell names;
Here, reference is being made to [Service Year] because Service Year is a column name and its value must be greater than 4
[Leadership Training]="Yes"; The above analysis is applicable here too because Leadership Training is column name and it must be "Yes" for it to return a true value.
"Yes"; Return Yes if both conditions are true
"No"; Otherwise, return No.

A Meera array is defined to be an array containing only numbers as its elements and for all n values in the array, the value n*2 is not in the array. So [3, 5, -2] is a Meera array because 3*2, 5*2 or 2*2 are not in the array. But [8, 3, 4] is not a Meera array because 2*4=8 and both 4 and 8 are elements found in the array. Write a function that takes an array of numbered elements and prints “I am a Meera array” in the console if its array does NOT contain n and also n*2 as value. Otherwise, the function prints “I am NOT a Meera array” ○ Test 1: checkMeera([10, 4, 0, 5]) outputs “I am NOT a Meera array” because 5 * 2 is 10 ○ Test 2: checkMeera([7, 4, 9]) outputs “I am a Meera array” ○ Test 1: checkMeera([1, -6, 4, -3]) outputs “I am NOT a Meera array” because -3 *2 is -6
Answers
The program based on the question requirements:
The Programfunction checkMeera(arr) {
for (let num of arr) {
if (arr.includes(num*2)) {
console.log("I am NOT a Meera array");
return;
}
}
console.log("I am a Meera array");
}
The function takes an array as input and iterates through each element using a for-of loop.
For each element, it checks if its double is also present in the array using the includes() method.
If found, the function prints "I am NOT a Meera array" and returns. If no such element is found, the function prints "I am a Meera array".

Which of the following if statements uses a Boolean condition to test: "If you are 18 or older, you can vote"? (3 points)
if(age <= 18):
if(age >= 18):
if(age == 18):
if(age != 18):
Answers
The correct if statement that uses a Boolean condition to test the statement "If you are 18 or older, you can vote" is: if(age >= 18):
In the given statement, the condition is that a person should be 18 years or older in order to vote.
The comparison operator used here is the greater than or equal to (>=) operator, which checks if the value of the variable "age" is greater than or equal to 18.
This condition will evaluate to true if the person's age is 18 or any value greater than 18, indicating that they are eligible to vote.
Let's analyze the other if statements:
1)if(age <= 18):This statement checks if the value of the variable "age" is less than or equal to 18.
However, this condition would evaluate to true for ages less than or equal to 18, which implies that a person who is 18 years old or younger would be allowed to vote, which is not in line with the given statement.
2)if(age == 18):This statement checks if the value of the variable "age" is equal to 18. However, the given statement allows individuals who are older than 18 to vote.
Therefore, this condition would evaluate to false for ages greater than 18, which is not correct.
3)if(age != 18):This statement checks if the value of the variable "age" is not equal to 18.
While this condition would evaluate to true for ages other than 18, it does not specifically cater to the requirement of being 18 or older to vote.

must be two vertices that have the same degree.
Answers
To prove that in a simple graph with at least two vertices there must be two vertices that have the same degree, we can use the Pigeonhole Principle.
How to do the proofLet G be a simple graph with n vertices. The degree of a vertex in G is the number of edges incident to that vertex. The degree of a vertex can range from 0 (if the vertex is isolated) to n-1 (if the vertex is adjacent to every other vertex in the graph).
Suppose for the sake of contradiction that all n vertices of G have distinct degrees. Then the possible degrees of the vertices are 0, 1, 2, ..., n-1, and there are n different degrees.
However, since there are only n vertices in the graph, there are only n possible degrees that the vertices can have. Therefore, by the Pigeonhole Principle, there must be at least two vertices in G that have the same degree.
This contradiction shows that our assumption that all n vertices of G have distinct degrees must be false, and thus there must be two vertices in G that have the same degree.
