Hello codeforces, my name is... or let me say, i love to call myself Mr_Algorithm because i like to solve algorithmic problems, and i am training for ACM, really really training hard, solving hard graph problems, interesting dp problems, amusing data structures like: Segment tree, trie, stack ... training for hard things, like flows and maximum matching... I mean anything you need to know to reach the world finals :D

But, yesterday i discovered that all my training was useless, when I participated in the Nationals in my country, a problem set with 12 problems, NO graph!!! one dp problem but it was about 80% geometry 20% dp, another three geometry problems, NO data structures, NO real algorithms, just a punch of some silly & hard implementation problems, that requires no thinking, but just coding for hours!!!

Anyway, I want to help the new Acmers in my country by suggesting adding "3tes" tag to Codeforces tags, so that new Acmers won't waste there time by training with stupid & useless algorithmic problems, just solve "3tes" problems and you will reach the WF for sure.

Mr MikeMirzayanov although most codeforces problems are awesome and great, but i can help you choosing some "3tes" problems like this and this perhaps this might help the new Acmers in my country...
