Binary Search Tree Insertion (Implementation)

Explore how to implement Binary Search Tree insertion both iteratively and recursively in Python. This lesson helps you understand the step-by-step process of inserting values into a BST, organizing nodes efficiently, and writing clean, maintainable code for tree data structures.

Introduction

There are two ways to code a BST insert function

  • Iteratively
  • Recursively

We will be implementing both in this lesson. We’ll end up with the following tree once we implement the BST insert function and insert the elements [6,4,9,5,2,8,12,10,14].

%0 6 6 8 9 6->8 4 4 6->4 7 8 8->7 12 12 8->12 5 5 4->5 3 2 4->3 10 10 12->10 14 14 12->14
