观察单词表可以发现: 对于长度为3的单词,前两个字母相同的单词不超过7个 对于长度为4的单词,前两个字母相同的单词不超过35个 于是首先$O(26*26*nm)$预处理出 s1[x][i][j]表示(i,j)右上角里面字母x的出现次数 s2[x][y][i][j]表示(i,j)右上角里面单词xy的出现次数 枚举一个点,计算长度为1的单词的出现次数 枚举两个点,计算长度为2,3,4的单词的出现次数 总时间复杂度为$O(kn^2m^2)$,k不超过43 #include<cstdio> #incl…

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…

我们可以用Monad Reader来实现依赖注入(dependency injection DI or IOC)功能.Scala界中比较常用的不附加任何Framework的依赖注入方式可以说是Cake Pattern了.现在通过Monad Reader可以实现同样功能,两者对比优点各有千秋.所谓依赖注入是指在编程时使用了某个未知实现细节的对象,但依赖注入确保这个对象在这段程序运行时已经实例化.这种需求通常是在大型软件开发时对项目进行模块化分割后虽然模块之间互有依赖,但又可以同步开发.特别是在多人…
