What is the preorder traversal, mid-order traversal and post-order traversal of binary trees?

What this article shares to you is about the pre-order traversal, middle-order traversal and post-order traversal of the binary tree. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

(1) preorder traversal

A, access the root node; b, preorder traverse the left subtree; c, preorder traverse the right subtree.

(2) Intermediate ergodic

A, traverse the left subtree in the middle order; b, access the root node; and c, traverse the right subtree in the middle order.

(3) Post-order traversal

A, traverse the left subtree in post-order; b, traverse the right subtree in the following order; c, access the root node.

Remember!

The above is what the pre-order traversal, middle-order traversal and post-order traversal of the binary tree is. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
