Strengths:

• The code is clean, well-commented, and easy to understand.
• The MinStack implementation is efficient and correctly handles all operations in O(1) time.
• The use of standard Java collections (HashMap, Stack) demonstrates good familiarity with the language.

Areas for Improvement:

• For the HashSet problem, using a HashMap is not the most space-efficient solution. Consider implementing a custom hashing mechanism with a 2D boolean array to reduce space usage.
• The remove method in HashSet has a logical error: it checks if (!contains(value)) before removing, which means it will never remove anything. This should be removed or corrected.
• The MinStack could include null checks or handle edge cases more gracefully, though the current implementation is functionally correct.
