So sad :(

In Round 206, Div. 1 E, I submitted about 10 times and all of them got "Denial of Judgement". I copied another solution for checking out but it got the same result, so I wonder why it happened ,and it seems that many people have this problem too...

See my status at http://codeforces.com/contest/354/submission/5026557 and http://codeforces.com/contest/354/submission/5026515 (copied one).

It looks like always being crashed at the 17-th point ...
