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) … WebJun 16, 2024 · To detect if there is any cycle in the undirected graph or not, we will use the DFS traversal for the given graph. For every visited vertex v, when we have found any adjacent vertex u, such that u is already visited, and u is not the parent of vertex v. Then one cycle is detected. We will assume that there are no parallel edges for any pair of ...
