Closest Binary Search Tree Value
Explore how to identify the node in a binary search tree whose value is closest to a given floating point target. Understand constraints on node values and tree size, and practice implementing a depth-first search approach to solve this common interview problem efficiently.

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
