Kth Smallest Element in a BST

Explore methods to identify the kth smallest element in a binary search tree through depth-first search. Understand problem constraints, practice building logical solutions, and learn to implement efficient algorithms that balance time and space complexity in tree data structures.

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. ...
