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 .
