Detect Cycle in Directed Graph 有向图找环 Given n nodes labeled from 0 to n - 1 and a list of directed edges (each edge is a pair of nodes), write a function to check whether the graph contains a cycle. if edges = [0, 1], [1, 2], [0, 2]], it means 0 -> 1, 1 ->...
Dectect cycle in directed graph: Detect cycle in a directed graph is using aDFS. Depth First Traversal can be used to detect cycle in a Graph. DFS for a connected graph produces a tree. There is a cycle in a graph only if there is aback edgepresent in the graph. A back edge is an...
DirectedGraph g(4); g.addEdge(0,1);//g.addEdge(0, 2);g.addEdge(1,2);//g.addEdge(2, 0);g.addEdge(2,3);//g.addEdge(3, 3);cout <<g.isCyclic();return0; } Detect cycle in an undirected graph https://www.geeksforgeeks.org/detect-cycle-undirected-graph/ 无向图就简单很...
Given a directed graph containing n vertice (numbered from 1 to n) and m edges. Can you tell us how many different Hamiltonian Cycles are there in this graph? A Hamiltonian Cycle is a cycle that starts from some vertex, visits each vertex (except for the start vertex) exactly once, and...
