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. WebThe DFS algorithm works as follows: Start by putting any one of the graph's vertices on top of a stack.
