说明：  acm是大学生程序竞赛中最常见的，对于一个程序员而言，参加acm不仅能够拓宽自己的知识面，而且能够在参加比赛的同时，认识一些新的朋友，而这些朋友可能在以后的生活中，对你产生很大的影响，对于一个非专业的程序员来说，如果能够参加acm竞赛，那么不仅能够培养自己的兴趣爱好，而且更能巩固知识面！
(ACM is the most common in the program competition for college students. For a programmer, taking part in ACM can not only broaden their knowledge, but also be able to meet some new friends while participating in the competition, and these friends may have a great impact on you in the future, for a non professional programmer. For example, if we can participate in the ACM competition, we can not only develop our interests, but also consolidate our knowledge.)
