spoj.pl/problems/SOLDIERS/
i am relatively new to python. with try block it gives WA (im guessing because my code doesnt produce output for certain cases) ,with the try block it gives NZEC.
is my logic wrong? if not, how do i fix the nzec problem. thanks

for i in range(input()):
    #try:
        a,b=map(int,raw_input().split(' '))
        #logic removed
    #except:continue

If you're using Py2.5, you shouldn't use //,
If you're using Py3.1, you shouldn't use raw_input.

Make a choice.

thank you
i modified my code and this is how it looks now. i still get NZEC. (and WA with the try block)

for i in range(int(raw_input())):
    #try:
        a,b=map(int,raw_input().split(' '))
        #logic removed
    #except:continue

Try this one:

1
2 3

i get 3 as output. I guess some part of my code is not consistent with py2.5 standards. i'm using a Python 2.7.3 interpreter so i don't know

There is no problem with the Python version. It's just that your algorithm is wrong: 3 is not the correct output for the given input.
The NZEC is simply because of a malformed input data: if you use split without a delimiter you have no problems with that.
