Hello everyone! I'm new on codeforces and programming. It's my first blog entry. Sorry for my mistakes. I know some algorithms but I can't use them in contests. I ask you books for easy (beginner) or (elementary) algorithms that every programmer should know. I would be glad if someone helps me to be a good programmer. I want to solve at least 3 or 4 problems from div2. I know that it is not impossible.

IMO, firstly, you should solve problems DIV2-A, DIV2-B from problemset. They are simple but need some skill of writing code.
When you'll be able to solve every A/B problem, try to solve DIV2-C and maybe DIV2-D problems. If you cannot solve some one, read the editorial and write own solution by your hands. Usually these problems need knowledge of some algorithms, which you can learn in process. The book which can help you learn algorithms.
Good luck! :)
Thanks a lot!!!
