Answer:

Best-case = 2 gloves

Worst-case = 12 gloves

Explanation:

  • For the best-case: Because there is a chance that you take two gloves of the same color in the first two round the answer is two.
  • For the worst-case: The worst case would be if, for each color-group of gloves you take the right or left glove, for example, you take 5 left-hand red gloves then 4 left-hand yellow gloves, then 2 left-hand green gloves, because you have already taken all of the left gloves the next one is going to be a right glove that is going to pair with one of the already selected gloves, therefore, the answer is 12 -> 5+4+2+1 = 12

Create a new class MyArray_DE and copy and paste the previous program. Be sure to rename the class to MyArray_DE. Modify the pro
vova2212 [387]

Answer:

public class MyArray_DE

{

public static void main(String[] args) {

    int[] numbers = {28, 7, 92, 0, 100, 77};

    int total = 0;

    for (int i=0; i<numbers.length; i++){

        if(numbers[i] % 2 == 0)

            total += numbers[i];

    }

 System.out.println("The sum of even numbers is " + total);

 System.out.println("The numbers in reverse is ");

 for (int i=numbers.length-1; i>=0; i--){

        System.out.print(numbers[i] + " ");

    }

}

}

Explanation:

Since you did not provide the previous code, so I initialized an array named numbers

Initialize the total as 0

Create a for loop that iterates through the numbers

Inside the loop, if the number % 2 is equal to 0 (That means it is an even number), add the number to total (cumulative sum)

When the loop is done, print the total

Create another for loop that iterates through the numbers array and print the numbers in reverse order. Note that to print the numbers in reverse order, start the i from the last index of the array and decrease it until it reaches 0.
