Your solution for validating BST is correct and efficient. The recursive approach with min and max boundaries is a standard and effective method. The time and space complexities are optimal.

However, note the following:

• The class name should be "Solution" if you are submitting on LeetCode, as the problem expects a class named Solution with the method isValidBST.
• The BuildTree.java file is not relevant to the Validate BST problem. Make sure you are submitting only the code for the problem at hand.

If you intended to submit both files for different problems, that is fine, but for this evaluation, we are only considering the Validate BST problem.

Overall, your solution for Validate BST is excellent.
