Solution: Closest Binary Search Tree Value
Explore how to identify the closest value to a floating point target in a binary search tree by leveraging BST properties. Understand how to traverse efficiently using depth-first search, compare distances, and update your closest candidate, all while maintaining optimal time and space complexity.

Statement
Given the root of a binary search tree and a floating point target value, find the node value in the BST that is closest to target. If there are multiple node values with the same minimum distance to target, return the smallest among them.
Note: The
targetis a floating point number, while all node values are integers.
Constraints:
The number of nodes in the tree is in the range
