题意:链接
方法:乱搞
解析:
出这道题的人存心报复社会。
首先这个单词表…先上网上找这个单词表…
反正总共2265个单词。然后就考虑怎么做即可了。
刚開始我没看表，找不到怎么做，最快的方法我也仅仅是想到了类n^6的做法。
然后我就卡关辣，这关怎么过！
神犇的方法是:观察表。发现规律:
发现表中的单词最长就是4个字母。
所以我们能够考虑求1，2，3，4长度的单词数。
1的话能够直接记录，扫的时候顺带加上即可。
然后神犇说了一句话:
表中长度为4的单词前两个字母同样的单词个数不超过35个。
长度为3前一个字母同样的单词个数不超过7个。
所以直接上链表优化啊？
这种话就要求我们预处理什么呢？
预处理点（i,j）右上角字母x的出现次数。
预处理点（i,j）右上角后缀xy的出现次数。
这个怎么维护啊？
容斥原理啊，所以复杂度在26*26*nm左右，也就是4次方，能够接受。
所以我们仅仅须要枚举开头的两个字母，这是n^4的复杂度，然后再加上链表，枚举次数不超过43=(35+7)。而提取个数由于我们的预处理，变成辣O1啊。所以这种话总共的复杂度是在n^5的。
掉了一个n啊！
这不就能过了吗！
