Depends on inorder, pre and post order.

This is technically preorder depth-first traversal, not DFS. You’re not searching for anything and you don’t exit early like DFS does.

Honestly, all the tree traversal algorithms except hierarchical decomposition are trivial when implemented recursively. Things only get slightly tricky when you need to do it iteratively.

Thank you for adding learn-scrolling content.

This is preorder traversal of a binary tree. DFS doesn’t need to be applied to a tree, and doesn’t have to be preorder when it does apply to a binary tree.

I have programming knowledge but I can't build a whole code without any references, please tell me what should I do?
