Which loop is faster?


for (I = 0; I < N; I++)
  for (J = 0; J < M; J++)
    update(Xs[I][J]);
or

for (I = 0; I < N; I++)
  for (J = 0; J < M; J++)
    update(Xs[J][I]);
???

And just in case you have me filtered...

Geeze, this would be easier if you just wrote some code...

public class Main {

    public static void main(String[] args) {
        int x = 5;
        int y = 0;
        int z = 0;

        try {
            z = x/y;
        } catch (Exception e) {
            System.out.println("Can't divide by zero");
        }
       
    }
}


And the result...

run:
Can't divide by zero
