Implement Hash Set (Design HashMap.java)

Strengths:

1. Correct implementation of the two-level hashing approach
2. Proper handling of edge case for key 1000 (bucket 0 with extended size)
3. Clean code structure with good separation of concerns
4. Efficient O(1) operations for all three methods

Areas for Improvement:

1. The comments section is empty - add documentation explaining the approach, time/space complexity
2. Variable naming is slightly inconsistent (e.g., primaryb vs getprimaryhash) - consider using more descriptive names like primaryBuckets
3. Could add input validation for edge cases (though constraints guarantee valid input)
4. Consider adding toString() or debugging support for easier testing

Overall, this is a solid implementation that matches the reference solution's approach and performance characteristics.

VERDICT: PASS

Implement Min Stack (MinStack.java)

Strengths:

• Correctly implements the two-stack approach for O(1) minimum retrieval
• Clean, readable code with good variable naming
• Proper initialization of min to Integer.MAX_VALUE
• Correctly updates min after pop by peeking from minst

Areas for Improvement:

• The reference solution initializes minSt with a push of Integer.MAX_VALUE in the constructor, which provides a safety net. Your solution doesn't do this but still works correctly since min is only accessed after at least one push.
• Consider adding null checks or validation if this were production code, though for this problem's constraints it's not strictly necessary.
• The solution is already optimal for this problem - no significant optimizations needed.

The solution is correct, efficient, and well-written. It differs only in minor style choices from the reference solution while maintaining the same algorithmic approach and complexity guarantees.

VERDICT: PASS
