In the last lesson, we learned about different types of trees, how they're constructed, and what they're used for. In this lesson, we'll learn two different methods for visiting the nodes in a tree.

Learn how to traverse a binary tree in pre-order, in-order, and post-order using Python. Find out when to use each method and how to ace binary tree interview questions.

To write clean and readable binary search tree (BST) traversal code, choose the right method for your task, like in-order for sorted output or pre-order for serialization.

Is there any way to implement a nonrecursive preorder traversal of a binary tree without using a stack? In a standalone function?the recursive preorder ...
