solution of B problem(DIV 2)!

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.
