WebCycle in undirected graphs can be detected easily using a depth-first search traversal. While doing a depth-first search traversal, we keep track of the visited node’s parent along with the list of visited nodes. During the traversal, if an adjacent node is found visited that is not the parent of the source node, then we have found a cycle in ... WebDec 28, 2024 · Union-Find Algorithm can be used to check whether an undirected graph contains cycle or not. Note that we have discussed an algorithm to detect cycle. This is another method based on Union-Find. This method assumes that the graph doesn\’t contain any self-loops. We can keep track of the subsets in a 1D array, let\’s call it parent[].
