DFS (Depth-First Search) and BFS (Breadth-First Search) are two of the most important graph and tree traversal algorithms used in coding interviews, competitive programming, and real-world software ...

Nodes 0, 1, and 2 form a cycle. If we remove 0 - 1, the graph remains connected. However, removing 1 - 3 disconnects nodes 3 and 4 from the rest of the graph.
