Depth First Traversal can be used to detect cycle in a Graph. DFS for a connected graph produces a tree. There is a cycle in a graph only if there is a back edge present in the graph. A back edge is ...

Cycle is a path of edges that traverse from a node to itself or from a node to its starting vertex. For cycle detection, Depth First Traversal (DFS) can be used to detect cycle in the graph and able ...
