Solution: Validate Binary Search Tree
Understand how to validate a binary search tree by performing an in-order traversal and checking the order of node values. This lesson helps you implement a recursive solution that confirms if each node maintains BST properties, improving your skills in tree traversal and algorithm design.

Statement
Given the root of a binary tree, check whether it is a valid binary search tree (BST).
A binary tree is a valid BST if for every node:
-
The left subtree of a node contains only nodes with keys less than the node’s key.
-
The right subtree of a node contains only nodes with keys greater than the node’s key.
-
Both the left and right subtrees are valid BSTs.
Constraints:
-
