WebA path that starts from a given vertex and ends at the same vertex traversing the edges only once is called a cycle. Example : In the below graph, there exists a cycle between vertex 1, 2 and 3. Note: 1. There are no parallel edges between two vertices. 2. There are no self-loops(an edge connecting the vertex to itself) in the graph. 3. 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. high byte address

"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. " - Detect cycle in undirected graph striver
