A clique is a complete graph, in which there is an edge between every pair of the vertices. Given a graph with N vertices and M edges, your task is to count the number of cliques with a specific size S in the graph.  InputThe first line is the number…

题目传送门 题目大意:给出n个点,m条无向边,让你计算这幅母图中有几个大小为s的完全图. 完全图的意思是任意一个点都和其他点直接相连,完全图的大小指的就是完全图点的个数. 思路:比较巧妙的构图方式.我们会很自然地想到用dfs来找环,然后记录路径,判断是否成完全图,但是由于题目给的是双向边,如果直接构图的话,就会导致出现很多没有必要的情况,重复计算,爆栈超时. 所以在建图的时候只建从小的点到大的点的单向边,然后对n个点从小到大进行dfs,这样可以既可以保证不会有遗留的情况,也不会重复计算(因为每次…
