There are link two same submissions. In this problem first submission is sent at 2012-12-05 18:18:36 and it got Accepted. And the second submission sent today but it got TLE. I don't understand what's going on Codeforces. Could anybody help me? Thanks.
Lots of Codeforces users English is not main language so their English is not good enough. Problemsetting please just write a question , inputs and outputs please do not write long story not about question. Sorry for my bad English. Thanks. MikeMirzayanov
