HDU月赛

今天被虐了5个小时。一整天就做了两道题。果然，ACM和OI差别还是非常大的。。。

一开始看到前两题，数学，直接放弃。然后看到第3题，感觉很简单，因为之前做过一个类似的，而且比这个还要难，算是加强版，所以1A秒杀。然后切出去看problem list。发现最后一题最多人AC，就去做最后一题。做了才发现代码量非常大，接近两百行，如果有模板，应该是水得。。。不过很可惜，我不是职业acmer，没有模板，所以。。。敲了N久，调试了大概1.5个小时，1A！

然后回看第2题，用等比数列求和公式把数列的通项先推出来，然后发现实际上是求x^n mod a0=1所对应的最小的n值，然后与肥闽讨论了N久，决定暴力。然后TLE，MLE。。。换了3种hash，全部挂掉了。。。于是，再次果断放弃。

然后最后看到第4题也比较多人A，然后就去做，写了个200+行的A*，还没调出样例，比赛结束了= =

虽然比较悲剧，但是也居然排到了13名。。。

最后发现一点，数学差得太远了，差得更远的是英语。。。

另外，YM DIY群的AC大牛和UranusX大牛。。。就是第一和第四那两只。。
