final int[] mx = {0, 0, 1, -1};
final int[] my = {1, -1, 0, 0};
i found the above line of code, in many solution that was related to matrix
(NxM). but i could not understand how it is being used. can any one explain
a bit. or give any link reference where i can find some short of
explanation related to this.
half thanks in advance and the other half after answering....
