Hello all I am trying to solve this problem[1] [1] http://www.spoj.com/problems/MAIN12C/
As I remember, and as it still appears, this site severely penalizes Python solvers by using the same time limit for all languages. Thus, a 'slow' python program may work correctly but the site will not let you know. A test that refuses to answer is no test at all. In the meanwhile, an algorithmically equivalent C program will be run and judged correct, so the programmer can try to speed up while not losing correctness.
By teaching 'speed before correctness", this site promotes bad programming habits and thinking (and the use of low-level but faster languages). I quote your later response: "Now I am getting wrong answer so at least program is faster then previous one". If the previous one was correct and the revision wrong, you should toss the revision and go back to the correct program.
I recommend that you work on problems where you have tests that you can actually run even before you code.
