What is Clone Graph?
Given a connected undirected graph, return a deep copy of it. You use DFS or BFS and a hash map to track which nodes have already been cloned, so you do not create duplicate copies when revisiting nodes. This problem teaches you to handle graphs with cycles during traversal, which requires tracking visited nodes from the start.
