This is the first article and the start of the way going to ACM.I am not that strong bull,but I just do everything I can to achieve it. From now on, for each problem I ac, I will put down some thought and ideas,I think, that will be good to help me out of some kind of puzzled mind.
OK,Let's move.
Good luck!
