You have been tasked with writing a program to help score 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}
};

What does the following mystery method do?

public int mystery(int[][] scores) {
    int x = 0;
    int y = 0;
    for (int row = 0; row < scores.length; row++) {
        int a = 0;
        for (int col = 0; col < scores[0].length; col++) {
            a += scores[row][col];
        }
        if (a > x) {
            x = a;
            y = row;
        }
    }
    return y;
}
