Runtime Error (NZEC) in simple code

Question

I\'m getting runtime error (NZEC) when running the following code over at SPOJ. I\'d be very thankful if any of you would kindly point out what\'s going on.

Answer 1

I had the same message while programming in java. It turned out I should have put my source code in default package (or not change package at all). I hope this helps someone.
