E.g., comparisons, comparisons, comparisons.

VERDICT: NEEDS_IMPROVEMENT

---

Construct Binary Tree from Preorder and Inorder Traversal (problem 2- leetcode105.py)

Strengths:

• Correct implementation of the algorithm
• Optimal time and space complexity matching the reference solution
• Clean, readable code with good documentation
• Proper use of dictionary comprehension for the hash map
• Good use of type hints in the docstring

Minor Suggestions for Improvement:

• Consider using self.idx as a parameter or wrapping it in a closure for slightly cleaner code organization, though this is purely stylistic
• The comment header at the top is good practice for documenting complexity
• Could add a brief comment explaining the algorithm's approach for future readers

Overall, this is an excellent solution that demonstrates a clear understanding of the problem and implements it efficiently.

VERDICT: PASS
