The Problem Solving Guide v1.0

This site will contains *unofficial hint/guide to solve many problem set from the programming contests. Warning: there is NO SOLUTION here, just a hint or some important case. You still have to solve it yourself. Of course, if you still confused on how to solve the problem, you can always ask me via e-mail ^_^

Anyway, problem will be group by its contest. ACM, CEOI, IOI, and many others, including online contest from Valladolid and Timus, and local contest in my country, Indonesia. For local contest, hint will be available in Indonesian language, since the problem also provided in Indonesian. Also, since there are so many problems, I will add one by one, in my spare time. So please be patient :) Don't forget, you can always help me by sending me your hint/guide that are not available here yet, or maybe more efficient than I mention here.

For those who still learning, there are some quick useful algorithm guide in here, like DFS, binary tree, LCS, and some others. No technical expanation, just a simple explanation on them and how to implement them. Actually, i made it for myself (yes, I'm still learning too ;), since I don't have enough memory to memorize all the algorithm ;p

Hope you enjoy it and have a nice programming day :-)
