Today is first time I see it, there are algorithm on the Codeforces...but I do not know where I can learn it, the algorithms. Therefore, I ask your help, where I can obtain new knowledge with the algorithm? I know this may be question in repeat, but I am new and cannot search it. I feel quite dumb right now, I cannot solve many of the B problem...they need the many of the algorithms. But I still am incapable of learn those algorithms :(. It's a very sad story~~
