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. WebDFS Algorithm. Step 1: Create an empty boolean array representing the nodes’ state (visited or unvisited). Initially, all nodes are unvisited, so the entire array is initialized with false. Step 2: Choose a starting node. Then initiate a recursive function with the …
