Solution: Closest Binary Search Tree Value
Explore how to identify the node value in a binary search tree closest to a given target. Learn to efficiently traverse the BST by using its properties to compare distances and select the smallest closest value, improving search speed and accuracy in tree-based problems.

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
