Detect cycle in a undirected graph
WebFeb 15, 2024 · To detect a cycle in a directed graph, we'll use a variation of DFS traversal: Pick up an unvisited vertex v and mark its state as beingVisited For each neighboring vertex u of v, check: If u is already in the beingVisited state, it clearly means there exists a backward edge and so a cycle has been detected WebInterview_DS_Algo / Graph / Detect cycle in an undirected graph (BFS).cpp Go to file Go to file T; Go to line L; Copy path Copy permalink; This commit does not belong to any …
