Solution: Two Sum IV - Input Is a BST
Explore how to implement a breadth-first search to determine if two nodes in a binary search tree add up to a given integer. Understand using sets to track complements during traversal and analyze the time and space complexity of this approach.

Statement
Given the root of a binary search tree and an integer k, determine whether there are two elements in the BST whose sum equals k. Return TRUE if such elements exist or FALSE otherwise.
Constraints:
The number of nodes in the tree is in the range
