If there is any self-loop in any node, it will be considered as a cycle, otherwise, when the child node has another edge to connect its parent, it will also a cycle. For the disconnected graph, there may different trees present, we can call them a forest.

BFS wont work for a directed graph in finding cycles. Consider A->B and A->C->B as paths from A to B in a graph. BFS will say that after going along one of the path that B is visited. When continuing to travel the next path it will say that marked node B has been again found,hence, a cycle is there. sar command for memory usage

"WebSep 26, 2024 · Initially all vertices are colored white (0). From each unvisited (white) vertex, start the DFS, mark it gray (1) while entering and mark it black (2) on exit. If DFS moves to a gray vertex, then we have found a cycle (if the graph is undirected, the edge to parent is not considered). The cycle itself can be reconstructed using parent array.

WebThe idea is to find if any back-edge is present in the graph or not. A digraph is a DAG if there is no back-edge present in the graph. Recall that a back-edge is an edge from a vertex to one of its ancestors in the DFS tree. Fact: For an edge u —> v in a directed graph, an edge is a back edge if departure [u] < departure [v].
