Hi Codeforces!

I have finished my bachelor's degree in computer science a few months, and I intend to keep studying in a master's degree. I really like problems with data structures, and I would like research this topic or something like that.

So, What kind of new data structure do you think that need to be create for the future? What kind of problem would this structure solve?

Hi codeforces,

Today, i received a email from "[email protected]" to registrate in contest. Obviously, it is a spam try to steal my username and password.

Someone received that?

Look this url!

Hi codeforces.... How I can delete the Gym contest that I have created? I can't find this function... :(

Hi Codeforces!

I'm trying solve this problem http://www.spoj.com/problems/ZQUERY/ . My code has complexity O( n * sqrt(n) * log(n) ) using Mo's algorithm and Segment tree. But, i get TLE. My code use std::deque to find the solution of each interval.

This data structure is slow in this case? Is there any way to remove log(n)?

Thanks for advance!
