WebDetect Cycle in a Directed Graph using BFS. We can also check whether the given graph has any cycles or not using the breadth-first search algorithm. The idea is to traverse the graph using BFS and check any path being repeated. If so, there is a circle in the graph. We use an additional Vertex variable ( parent) to keep track of traversed paths.
