Web2. Using DFS. The following graph contains a cycle 8—9—11—12—8: When we do a Depth–first search (DFS) from any vertex v in an undirected graph, we may encounter a back-edge that points to one of the ancestors of the current vertex v in the DFS tree. Each “back edge” defines a cycle in an undirected graph. If the back edge is x ...
