Codeforces Round #246 (Div. 2)
第一次打Codeforces的vp。。
毕竟人太弱
A Choosing Teams :十足逗比题，连语文题都算不上。搞搞就过了= =。
这都要贴代码？
B Football Kit :鸣谢 Dccxx
C Prime Swaps :题目大概就是给你一个数组，让你交换其中的一对使得他们有序，但是对于交换的元素Ai, Aj，必须满足(j-i+1)为质数
大概就是把每个数应该到的地方求出来，然后不停的贪心swap离它最近的满足性质的位置，应该可以预处理出来，但我burn了个可爱的写法，然后就爆了一发OJ，原来是数组开小了。哈哈、
这都要贴代码？
D Prefixes and Suffixes :鸣谢 Dccxx
E Square Tiling :给你一个n*m的矩形，让你填充正方形，然后让方案的字典序最小，每次放最大的正方形就可以了，线节问题在良心的样例之下，burn掉了、
这都要贴代码？
