Hi!

In Codeforces Round #407 (Div. 2) problem A,the worst case input was bigger than 256kb.

But there were some deque sources,and one particular source(http://mirror.codeforces.com/contest/789/submission/25911140) which instead of subtracting k,it subtracted 2k,and this was no longer TLE for the worst case that this limit allowed.

I think that for some problems the limit should be increased.What do you think about this situation? LE:apparently the source code got Ac.perhaps i didn't understand that source code
