I am doing a gym contest and I the problem says ( Input File: A.in ) & ( Output File: standard output ) and whenever I submit I got WA what I must do.

Thanks In Advance :)

Some times when I submit my code and went to the Contest status Table to see my submit and its progress in this link : (http://.com/problemset/status) it does not auto update the tests so i cant see my answer progress. is this from my internet or what?
