You have been tasked with writing a program that computes the average score for gymnasts at the olympics. You are given a 2D array of values. Each row in the 2D array represents the scores received in a single run. Each column of the 2D array represents the scores given by a particular judge.

For example, if a gymnast had 3 different runs, and 5 judges scoring each run, their scores 2D array might look like this

int[][] scores = {
    {9, 8, 9, 9, 10},
    {8, 10, 10, 9, 8},
    {7, 8, 7, 6, 7}
};

Which of the following programs will compute the overall average score of the given scores 2D array?

1. Correct Answer
   Incorrect Answer
   a

   int sum = 0;
   for(int row = 0; row < scores.length; row++){
       for(int col = 0; col < scores.length; col++) {
           sum += scores[row][col];
       }
   }
   
   double average = (double) sum / (scores.length * scores.length);
   System.out.println(average);

   Java
2. Correct Answer
   Incorrect Answer
   b

   int sum = 0;
   for(int row = 0; row < scores.length; row++){
       for(int col = 0; col < scores[0].length; col++) {
           sum += scores[row][col];
       }
   }
   
   double average = (double) sum / (scores.length * scores.length);
   System.out.println(average);

   Java
3. Correct Answer
   Incorrect Answer
   c

   int sum = 0;
   for(int row = 0; row < scores.length; row++){
       for(int col = 0; col < scores[0].length; col++) {
           sum += scores[row][col];
       }
   }
   
   double average = (double) sum / (scores.length * scores[0].length);
   System.out.println(average);

   Java
4. Correct Answer
   Incorrect Answer
   d

   int sum = 0;
   for(int row = 0; row < scores[0].length; row++){
       for(int col = 0; col < scores.length; col++) {
           sum += scores[row][col];
       }
   }
   
   double average = (double) sum / (scores.length * scores[0].length);
   System.out.println(average);

   Java
5. Correct Answer
   Incorrect Answer
   e

   int sum = 0;
   for(int row = 0; row < scores[0].length; row++){
       for(int col = 0; col < scores[0].length; col++) {
           sum += scores[row][col];
       }
   }
   
   double average = (double) sum / (scores[0].length * scores[0].length);
   System.out.println(average);
