The algorithm (using DFS): Create a hash map: original → clone Start DFS from the given node For each node: - If already in the map, return the existing clone - Otherwise, create a new clone, add to map - Recursively clone each neighbor - Set the clone's neighbors to the cloned neighbors Return the clone of the starting node
