Here’s the link to my answer to “Am I a Fibonacci Number” question from november cook-off :

Can someone please explain me why I get the Nzec error?
I think there were trailing spaces in the input file which lead to an exception.
I also faced the same problem.
I then used raw_input() along with typecasting to solve the problem.
Hope this helps
