• Strengths:

  • Correct implementation of the in-order traversal to validate BST.
  • Efficient use of a flag to skip unnecessary checks once an invalid condition is found.
  • Good handling of edge cases (e.g., null nodes).

• Areas for Improvement:

  • The method name helper could be more descriptive to reflect its purpose, such as inOrderTraversal.
  • The return statement in IsValidBST could be simplified to return flag; instead of the conditional check.
  • The comments in the code could be more detailed to explain the logic, especially for someone who might be reading the code for the first time.
