Closest Binary Search Tree Value
Explore how to identify the closest node value to a floating point target in a binary search tree through depth-first search traversal. Understand the problem constraints and apply logical steps to return the smallest value with minimum distance to the target. Practice implementing this approach to improve problem-solving skills involving tree data structures.

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
