WebGiven a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. For example, the following graph contains three cycles 0->2->0, 0->1->2->0 and 3->3, so your function must return true. Depth First Traversal can be used to detect cycle in ...

WebA Topological sort or Topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. Topological order is possible if and only if the graph has no directed cycles, i.e. if the graph is DAG. For example, consider the following graph: WebIn the recursive DFS, we can detect a cycle by coloring the nodes as WHITE, GRAY and BLACK as explained here.
