recursion is inherently dfs - well said. Watched a bunch of bfs videos but nobody mentioned it

The 1st one (Pre-Order) is DFS, not BFS.
Only the 2nd one is BFS.
Both are iterative, not recursive.

Thanks I’ve been working on this problem for days it’s frustrating because I make 0 progress

is preorder traversal really needed? cause we can access it using depth and then we can append easily based on depth in the result list
