Kth Smallest Element in a BST

Explore how to find the kth smallest element in a binary search tree by applying depth-first search strategies. Understand problem constraints and implement an efficient O(n) time and space solution with a hands-on coding challenge.

We'll cover the following...

Statement

Given the root node of a binary search tree and an integer value k, return the kthk^{th} smallest value in the tree. ...
