Implement Hash Set (design-1.py)

Strengths:

• Excellent implementation that matches the reference solution's approach
• Clean, readable code with good variable naming
• Proper handling of edge cases (bucket 0 needing extra space)
• Good documentation with time/space complexity comments
• Correctly implements all three required methods

Areas for Improvement:

• The hash function names (hash_func1, hash_func2) could be more descriptive (e.g., primaryHash, secondaryHash)
• Consider adding docstrings to the class and methods for better documentation
• The comment about "faced error in some syntax" suggests more practice with Python syntax would help

Note: The submission includes a Min Stack solution that wasn't part of the original problem. For future submissions, focus on only the requested problem to avoid confusion.

VERDICT: PASS

---

Implement Min Stack

Strengths:

• The two-stack approach is correctly implemented
• Time complexity is optimal at O(1) for all operations
• Code is clean, readable, and well-commented
• The duplicate strategy for min_stack is an efficient space optimization
• Proper handling of edge cases (using <= in the condition)

Areas for Improvement:

• The file contains unrelated code (HashSet implementation) that should be separated
• The class could benefit from type hints for better code documentation
• Consider adding docstrings to the class and methods for professional documentation

VERDICT: NEEDS_IMPROVEMENT
