WebJul 30, 2024 · For the directed graph, we will start traversing from all nodes to check connectivity. Sometimes one edge can have only outward edge but no inward edge, so that node will be unvisited from any other starting node. In this case the traversal algorithm is recursive DFS traversal. Output: The Graph is connected. theraband wrist exercisesWebApr 28, 2016 · Use pre-increment instead of post-increment in the for condition (no useless copying).
