Hey there, I am new on codeforces and I wanna train, therefore I might represent my country in the upcoming ACM or even ICPC. I felt like there is a gap between the B and C problems difficulty, most contests I viewed, problems numbered A ,B were very easy, however problems C, D, & so on were very difficult. I may think that this is the point I cannot pass , because I want to train on medium difficulty problems , what do you suggest? codeforces!
UPD1 I have improved a lot since last year! It was accomplished by studying many algorithms such as in Graph(dfs, bfs, dijkstra, topological sort) and in divide and conquer such as (dynamic programming, binary search) and data structure ( segment tree, trie, prim, BIT..). you can search Youtube for good tutorials for these algorithms/data structures. even though problems div1D div1E... still are very difficult.
The best method, I think, is to practice problems at the problemsets link and sort by number of solutions. This takes all of the problems on the website and lines them up in a way that you can take like a set of stairs — for the more times a problem has been solved, the easier it probably is (except for new contests). If you become bored with problems at any level, you can just skip ahead and find problems with fewer solutions.
Thanks for your feedback it was quit helpful
usually C problems and top problems require knowledge of algorithms, so you should start learning some algorithms :)
I guess you're right ,
I'm doing what alot of yellow and red coders suggested and that is to start solving problems in the first page of the most solved in the problem set and after you burn through the first four or five pages you will notice the difference #3tes :3
Thats sooo 3tes .... PLZ read what u have written again , & you'll discover something .... lol
If you really find them easy contact your coach "mr.3tees" and tell him that you're ready for "anti-omar".
(There are a lot of inside jokes here, if you don't get it please don't be mad at me)
lmfao .... mr 3tees has stuff 2 do, he is a temper guy, if I dont get what the heck he's talking abt from the first time !! he would crap in my mouth!!
Omar challenged mr.3tees and embarrassed him?
Omar is a cultural/ Historic character. Some people think he was a good guy, others think he was a bad guy. A specific group of people associate him with sin and bad stuff. So the joke is anything that gets you AC is an Anti-omar.

The 'science' of training in competitive programming by I_love_Hoang_Yen. Read it. :)
Awesome !! I regret that I've not read this before!
Auto comment: topic has been updated by Odin- (previous revision, new revision, compare).
My Congratulations :)
