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...
Welcome to Syria pro 3tes == SOI => Mr_Algorithm == member in SOI => Mr_Algorithm == dwik :D :D
bro*
How do you "like to solve algorithmic problems" and call them "stupid and useless problems" all in the same blog?
Are you writing this blog because you didn't qualify?
sorry for bad English , but in my opinion :
A --> dp ( hard )
C --> dp ( easy )
D --> dp ( annoying )
E --> basic geometry
I think most of us should have a good coach to tell us what to focus on and train really really hard
rather than wasting our time with unneccesary things ( specially in our region )
Geometry is very important for us , and we need this topic , but there was too much geomtry and that's sucks
finally , "3tes" is for ACMers not problems :p
