How to understand the preorder, middle order and post order traversal of python binary tree? aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

1. Preorder traversal: access the root node first, then the left subtree, and then the right subtree. (root node in front)

two。 Traversal in the middle order: first access the left subtree, then the root node, and then the right subtree (the root node is in the middle)

3. Follow-up traversal: first visit the left subtree, then visit the right subtree, and finally visit the root node (the root node is behind),

The left subtree is always in front of the right subtree, but only the root node is changing.

This is the answer to the question on how to understand the preorder, intermediate order and post-order traversal of the python binary tree. I hope the above content can be of some help to you.
