Thoughts on ACM, ACM Looking at the registration time on hang Dian, in October 29 last year, I took the road to the ACM algorithm competition. So far, I have seen more than half a year's experience with ACM and comments from the comment area. I suddenly found that I did not know what kind of mentality I took to

The end of the dream is another dream ---- ACM retired post, starting ---- acm When one thing that persists for three years suddenly tells you "Sorry, we're done ". What kind of mentality will you treat. If you don't have the first love, how can you stick to it later. Three years later, I finally quit the stage. --- If you don't have a passion, how can you be passionate? In September 24, 2011, I knocked o

Path to acm-path to acm by XiaoYu The mother function is also called a generative function. It was originally a mathematical term and is an important theory in composite mathematics. The generative function is to construct such a polynomial function g (x), so that the n coefficient of x is f (n ).For the primary function, we can see the following two sentences at most:1. "The addition law of the combination

We are still on our way to dream-Summary of the sixth ACM competition in Shandong Province, acm in Shandong Province The results of the competition reached expectations (Gold Medal), which is far from my expectation in terms of the process (the competition was too messy and I played poorly). Fortunately, my teammates resisted the pressure at the crucial moment, the consequences are really unimaginable. Warm
