Write a program to find the strongly connected components in a digraph. Format of functions: void StronglyConnectedComponents( Graph G, void (*visit)(Vertex V) ); where Graph is defined as the following: typedef struct VNode *PtrToVNode; struct VNode…

拓扑排列可以指明除了循环以外的所有指向,当反过来还有路可以走的话,说明有刚刚没算的循环路线,所以反过来能形成的所有树都是循环…

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…

Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Example 1: 0          3 |          | 1 --- 2    4 Given n = 5 and…

We will learn how to use withRouter() to inject params provided by React Router into connected components deep in the tree without passing them down all the way down as props. The app component itself does not really use filter. It just passes the fi…
