Strengths:

• The solution correctly implements the recursive range-checking method for validating BST.
• It handles edge cases with integer boundaries by using long min and max.
• The code is clean and easy to understand.

Areas for Improvement:

• The TreeNode class should not be redefined in the same file. The problem already provides the definition, so including it again may cause duplication. Remove the TreeNode class from ValidateBST.java.
• Although the solution is correct, note that the space complexity is O(h) due to recursion, which is efficient. However, in the worst case (skewed tree), h could be n, leading to O(n) space. This is acceptable and matches the reference solution.
• The solution for a different problem (ConstructBTFromPreAndIn) is included in the same submission. Make sure to only submit the code for the problem being solved.
