DIY: Binary Search Tree Iterator
Develop a BSTIterator class that allows efficient in-order traversal of a binary search tree. Understand how to implement the next() method to return the smallest element and the hasNext() method to check for remaining nodes. Gain hands-on experience with tree traversal techniques essential for coding interviews.

Problem statement
In this challenge, you have to implement a binary search tree iterator class called BSTIterator. The iterator will be initialized by the root node of the BST. You have to implement two methods:
next(): This will return the next smallest number in the BST.
