To check connectivity of a graph, we will try to traverse all nodes using any traversal … WebJul 30, 2024 · To check connectivity of a graph, we will try to traverse all nodes using any traversal algorithm. After completing the traversal, if there is any node, which is not visited, then the graph is not connected. For the undirected graph, we will select one node and traverse from it. In this case the traversal algorithm is recursive BFS traversal.
