I liked 297E - Mystic Carvings, mostly because of the emoticon-like figures :). It also has a very elegant solution.

      Amazing. Maybe you were lucky or submit it when the sever wasn't busy. I just copied your code and submit it and it get TLE!!! Here's the submission 3699691.

        server does not affect the speed of compiler, try to submit it many times because the running time of this code is nearby the time limit and there is a little bit difference between running time for each submit, so I think you will succeed after a few tries :)

          Yes. You are right. But you ARE lucky due to passed all tests in your first submission of this code :)

      clearly it's segment tree.

      you can find here tutorial for this problem.

      Segment tree. Actually I never understand segment tree and have many problems to code it for many problems, but I do code it for this problem. That's why I liked it. My code passed all tests using almost half of limits.

My favourite problem is 196B - Infinite Maze, from our contest. Idea: Hohol. Easy and tricky.

I think they are interesting. They need very few codes.
