Cycles

Cycles in a graph refer to a non-empty path of vertices in which the first and last vertices are equal. On the basis of the presence of cycles in a graph, a graph can be cyclic or acyclic. A directed graph without a directed cycle is called Directed Acyclic Graph(DAG). Cycle detection in a graph can be done by using Depth First Traversals. Cycles in graphs give rise to various other graph theory concepts like Topological Sorting and strongly connected components in directed graphs.
