What is the primary purpose of a binary tree's inorder traversal?

Step 1: Understand what a binary tree is. A binary tree is a data structure where each node has at most two children.
Step 2: Learn about binary search trees (BST). In a BST, the left child is always less than the parent node, and the right child is always greater.
Step 3: Know what inorder traversal means. Inorder traversal means visiting the left child, then the parent node, and finally the right child.
Step 4: Realize the order of visiting nodes in inorder traversal for a BST. This order will always give you the values in ascending order.
Step 5: Conclude that the primary purpose of inorder traversal in a binary search tree is to retrieve the elements in sorted order.
