Diagonal Difference

    Mine followed a similar logic, but you don't actually have to use two for loops. You already know the relationship between j and k, so you can use just one for loop to increment j.

    int rightD = 0;
        int leftD = 0;
        for(int i = 0; i < n; i++){
            leftD += a[i][i];
            rightD += a[i][n-i-1];
        }
        System.out.println(Math.abs(leftD - rightD));
