NZEC error in NSQUARE

[purplepen]

I have solved NSQUARE in C. But when I wrote the same code in python 2.7 I got an NZEC error.
My code goes like this:

n,p = [int(x) for x in raw_input().split()]
...
a sequence of 4 if else conditions and print statements.
that is all
if condition A:
print(X) // X is some number obtained after a modulo operation
elif condition B:
print(Y)
and so on.
Please help me out.

import sys
n,p=map(int,sys.stdin.read().split())
#...

gave me AC in 0.00s in Py2.5, and 0.09s in Py3.1 (0.05s with a better code)
It seems there's 9 test files.

I replaced the first two lines in my program with yours but I am still getting an NZEC error. Are you doing something differently here?

[francky]

Nothing special, only some if and some print and some %,
you can PM me your code if you want, I'll tell you more ...

An idea : be careful about the difference between Py2.5 and Py2.7, the server is labeled 2.7, but it's 2.5 in fact and there's some little difference in the language use.

Edit : I too got NZEC with other input reading.
There should be some files with n and p on separate lines.

I recommend to use here the following input reading method :

import sys
n,p = map(int, sys.stdin.read().split())
# do the job
