Welcome to this video on Binary Search Trees! We'll be diving into how to implement one in C++. Get ready to learn!

A Binary Search Tree, or BST, is a special type of tree where each node's left child is smaller and each node's right child is larger. This structure allows for efficient searching, insertion, and deletion.

Let's start by defining the structure of a single node in our tree.

Here's our Node structure. It's simple: an integer to hold the data, and pointers to the left and right child nodes.

Now, let's build the BinarySearchTree class to manage our nodes.

We'll have a private root node pointer and public methods for insertion, searching, and traversal.

The insert function starts the recursive insertion process.

This recursive helper function does the actual insertion, placing the new node in the correct position based on its value.

Let's visualize the insertion process. See how the new nodes are placed to maintain the BST property?

Let's see how to use our BinarySearchTree class.

Here's a simple main function demonstrating insertion and inorder traversal.

And that's it! You've successfully implemented a Binary Search Tree in C++!
