WebDec 15, 2024 · Like directed graphs, we can use DFS to detect a cycle in an undirected graph in O (V+E) time. We have discussed DFS based solution for cycle detection in an undirected graph . In this article, the BFS based solution is discussed. We do a BFS traversal of the given graph. For every visited vertex ‘v’, if there is an adjacent ‘u’ such ... WebDec 21, 2024 · Solution 1: Intuition: The intuition behind this is to check for the visited element if it is found again, this means the cycle is present in the given undirected graph. For the first component , firstly we insert the first element of the graph by marking it as visited in the Queue having prev of the first element as -1.
