WebMar 22, 2024 · Approach: To find cycle in a directed graph we can use the Depth First Traversal (DFS) technique. It is based on the idea that there is a cycle in a graph only if there is a back edge [i.e., a node points to one of its ancestors] present in the graph. To … Given an undirected graph with V vertices and E edges, check whether it contains … Given a Directed Graph with V vertices (Numbered from 0 to V-1) and E edges, … Time complexity: O(V + E), where V is the number of vertices and E is the number … Insert Operation in Trie:.
