I am solving the problem CF1042C(https://codeforces.net/problemset/problem/1042/C). Then I meet some troubles:
The Checker comment tells me that "wrong output format Unexpected end of file — int32 expected", but I can't understand it.Could anyone help me explain it? I would extend my appreciation if were to you do me a favour.
This is my final submission: https://codeforces.net/contest/1042/submission/164962519
(Sorry for my poor English)
Seeing a person who asked a question, I answered a question yesterday on Codeforces. I, however, got a downvote (also an upvote) and now my contribution is negative.
I just want to try to help others, but it seems that it decrease my contribution. Did I do something wrong? How can I increase my contribution?
