Building a Binary Search Tree - Insertion Tutorial

In this hands-on video we build a binary search tree by inserting numbers one by one: 73, 98, 12, 45, 67, 10, 43, 11, 99, and 32. Watch exactly how each node finds its place following BST rules with no rearranging allowed.

We discuss why the tree becomes lopsided, calculate its height, and verify the in-order traversal is sorted. Great practice for anyone learning binary search trees.

Next videos will cover searching and deleting nodes.

If you're studying data structures, build along with me!
