Closest Binary Search Tree Value
Explore how to identify the node value closest to a given floating point target in a binary search tree. Understand key constraints, utilize depth-first search strategies, and practice implementing a precise solution that handles edge cases with multiple closest values.

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
