All Latin Squares (USACO)

一个搜索的题目，不过肯定是要剪枝的最简单的两个剪枝我想到了第一个：首先，第一行已经确定了，那么我们可以把第一列也确定，就按照升序，2，3，4，5……，这样的话，没生成这么一个square，我们就可以随便的去交换除了第一行后面的几行。他们的一个全排列就对应着一种组合，所以最后的答案乘以N-1的阶乘就可以第二个：这个其实是看来的，就是每次只要所搜完N-1行就可以了。因为剩下的一行必然存在一个解。其实这

模块化设计带来复杂性的降低，同时可能引入性能上的损失，比如书中对sum-odd-squares过程的两种写法，原来的写法枚举列表元素的过程散落在累积、过滤、映射的过程中，主要一次循环就够了，而通过三个高阶过程来操作反
