Strongly Connected Components A directed graph is strongly connected if there is a path between all pairs of vertices. A strongly connected component (SCC) of a directed graph is a maximal strongly connected subgraph. For example, there are 3 SCCs in…

[HDU6271]Master of Connected Component 题目大意: 给出两棵\(n(n\le10000)\)个结点的以\(1\)为根的树\(T_a,T_b\),和一个拥有\(m(m\le10000)\)个结点的图\(G\).\(T_a,T_b\)的每一个结点上都有一个信息,表示\(G\)中的一条边\((u_i,v_i)\).对于\(i\in[1,n]\),询问从\(T_a\)和\(T_b\)上分别取出链\(1\sim i\),将链上的信息所表示的边加入\(G\)中后,\(G…
