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 ...
