Detect cycle in a directed graph gfg
WebDec 3, 2016 · No, he wasn't testing you. You can detect cycles in a graph using just two colors, but the graph must be undirected in that case. Elaboration. What I want to emphasize is that graphs are of two kinds on the basis of the way edges are directed, when we have a graph when we have al the edges going forward as well as backward … 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.
