Post-Order Traversal

Learn about post-order traversal in a binary search tree and implement it in C#.

We'll cover the following

Introduction

In post-order traversal, the elements are traversed in the “left-right-root” order. First visit the left child, then the right child, and then finally the root/parent node. Here is a high-level description of the post-order traversal algorithm:

  1. Traverse the left-subtree of the currentNode recursively by calling the postOrderPrint() function on it.

  2. Traverse the right-subtree of the currentNode recursively by calling the postOrderPrint() function on it.

  3. Visit the current node and print its value.
