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。。

  1. 回复forverlin1204:额,当时我有个性质没想到于是直接上了个强连通+topsort,然后再逆拓扑序对树根遍历,最后统计。。。所以代码很长。。。大牛见笑了。。。
