WebFeb 8, 2009 · An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle. WebFind whether the graph contains a cycle or not, return true if a cycle is present in the given directed graph else return false. For Example : In the following directed graph has a cycle i.e. B->C->E->D->B. Note : 1. The cycle must contain at least two nodes. 2. It is guaranteed that the given graph has no self-loops in the graph. 3.

WebMay 2, 2024 · That only represents a cycle if the corresponding edge had not yet been travelled before. One way to make the algorithm work, is to store the edge on the stack, not just a node.
