The basic intuition for cycle detection is to check whether a node is reachable when we are processing its neighbors and also its neighbors’ neighbors, and so on. WebDuring the traversal of the current path, if we come to a node that was already marked visited then we have found a cycle. Algorithm : Detect_Cycle ( Node source_node ) 1.
