The best problem in the world

Did you solve that? What did you do? Binary search + idea or you did Some Other Algorithms

I can't recall actually what is the most beautiful problem I've solved. Cause whatever problem I solve, no matter how good it was, I used to forget about the problem after few days. Recently I solved All Possible Increasing Subsequences from lightoj. I had to try continuously 5 days in a row to solve it. When I found out the solution & got Accepted sign, the feelings was awesome. There is another problem. Though I didn't solved this by myself. Problem — Kquery — Spoj I read the tutorial from DarthKnight's blog post . That's not the problem that amused me, it was the idea how to solve this. that was one of the most beautiful idea I've ever seen.
Yeah. When you solve a problem after much time thinking on it and many unsuccessful submissions, you feel great! I'll never forget such problems.
I've some problems with my mind. Even if I stop practicing an algorithm in what I'm good at, I almost completely forget this algorithm. I just remember the very basic concept. Next time I try to solve with this, I've to read/learn it from very basic.
