I just got the hang of solving informatics questions, so forgive me for me newbieness. =) Currently I have only solved about 400 questions. 
Nice site btw. =)
I am not in any university at the moment but my favourite topic is on graph. I find graph questions interesting.
Do you do topcoder? Hope to see more contributions from you ;) --Rrenaud 15:37, 18 Aug 2005 (EDT)
Nope, I don't do it. Maybe I will try it in the futre. Thanks by the way. I will try to write up as I solve more questions on OJ. -- Roticv 19:59, 19 Aug 2005 (GMT +0800)
