As a tester, i would like to say that my programming level is not that good, i am only a newbie now.
But i believe that there's nothing that i can't do as where a person can reach depends on what a person plan to be.
I had give myself a plan before writing this and i hope others can give me some advice.
i think that Improve thinking ability is very important so that i will do some questions which don't need so much program but need to think for sometime.
i will make more friends on codeforces and chat with them about programing.
i hope that you can agree with me and Vote:"I like it" after reading this.
and i hope more and more people can send me message and make me as your frinnd.
Thanks Codeforces, and thank you.
