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

This error can also mean that the program does not work correctly that is the output is not the expected output... believe it or not this is a strong possibility that your code is just not doing what the question asks it to....

Quoting from the link given at the end ->

NZEC (non-zero exit code) - helps telling crash from WA with interpreted languages; WA = Wrong Answer.
