Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. For example, the following graph contains three cycles 0->2->0, 0->1->2->0 and 3->3, so your function must return …
WebLet's use the Union-Find algorithm to find cycle in an undirected graph. Find the edges from the graph. 1-2 2-3 3-4 3-6 4-5 1-5 As there are six vertices, we'll create six disjoint-sets. Consider the edge 1-2, FIND (1)=1 FIND (2)=2 UNION (1,2) S1,S2 will be merged to S1 and set-representative of S1 will now be 1. Consider the edge 2-3, FIND (2)=1 WebFeb 7, 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 …
