Detect A Cycle in Directed Graph using DFS - Tutorial
WebFeb 13, 2024 · Time Complexity: The time complexity of the above approach to detect cycles in a directed graph is O (V+E), where V is the number of vertices in the graph and E is the number of edges. This … WebDec 20, 2024 · Detect cycle in a directed graph. There is a cycle in a graph only if there is a back edge present in the graph. Depth First Traversal can be used to detect a cycle in a Graph, DFS for a connected graph produces a tree. If the graph is disconnected then get the DFS forest and check for a cycle in individual trees by checking back edges. galland michelet
