题目是说给出一个数字,然后以1到这个数为序号当做二叉树的结点,问总共有几种组成二叉树的方式.这个题就是用卡特兰数算出个数,然后因为有编号,不同的编号对应不同的方式,所以结果是卡特兰数乘这个数的阶乘种方案.因为数字比较大,所以要用高精度的方法也就是用字符数组来做,我分别写了三个函数,一个算加法,一个算乘法,最后一个打表,等打出表来最后只要判断一下输入的数是第几个,直接输出就行了,下面是我的代码,第一次写高精度的这种大数处理,可能看上去比较繁琐= = #include<iostream> #inc…

For a undirected graph with tree characteristics, we can choose any node as the root. The result graph is then a rooted tree. Among all possible rooted trees, those with minimum height are called minimum height trees (MHTs). Given such a graph, write…
