Hi!

I would like to know, in your experience, which ones are the most important topics in order to perform well the ACM ICPC regionals?

I've been studying basic data structures, ad-hoc problems, greedy, dp, graphs algorithms, etc. But it seems that I'm still to weak, I can't think in any AC solution for mostly problems when I read the worksheets in the live archive. I know that there is no a short way, but I want to use my time wisely.

Also, there is no teacher (in my institute) or friend disposed to give any advise in CP so me and my teammate have been studying always with internet resources. It this ok? I think that this has been a big wall to overcome.

Thanks in advance.
