Detect and print cycle in graph

WebSep 26, 2024 · Here is an implementation for undirected graph. Note that in the undirected version, if a vertex v gets colored black, it will never be visited again by the DFS. This is because we already explored all connected edges of v when we first visited it. The connected component containing v (after removing the edge between v and its parent) … 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. Mark the source_node as visited. 2. Mark the source_node as in_path node. 3. For all the adjacent nodes to the source_node do. 4.
