WebJul 28, 2024 · An undirected graph is a set of nodes and edges, such that an edge signifies bidirectionality. Any path with 1 or more duplicates of any node(s) present in the path is known as a cycle A graph containing a cycle is called cyclic. We can solve the problem of detecting a cycle in an undirected graph by using dfs or bfs.
