I don't think write a blog will get more exposure. But I think I should write it.

I find 2014CAIS01 copy applese 's problem C and D (or cheat in the contest, I don't know).

To find the details, see: http://mirror.codeforces.com/blog/entry/61450#comment-454364

And cubercsl , which may be another handle of 2014CAIS01 cheat in last contest, see http://mirror.codeforces.com/blog/entry/8790#comment-452899 .

I don't know what should I say. You are a master(2200+), why you always try to copy?
