"output_1"
Example 2
Input:

Hints
Hint 1
Consider how BFS/DFS explores nodes and what it means for a node to be "visited" in the context of connectivity.
Hint 2
If the graph is undirected, what happens when BFS/DFS starts from a node and doesn't visit all nodes? What does this imply about connectivity?
Hint 3
For a directed graph, how would you modify BFS/DFS to check if all nodes are reachable from a given starting node? What additional checks are needed?
