Strengths:

• The code is well-organized and readable.
• The student has correctly implemented the required functionality for both problems.
• The use of docstrings and comments is excellent and helps in understanding the code.

Areas for Improvement:

• For the HashSet, consider using a more efficient data structure to achieve O(1) time complexity for operations. The current linked list approach can be slow for large datasets.
• The MinStack implementation is good, but the student mentioned having doubts about the approach. It would be beneficial to understand why the two-stack approach works and how it maintains the minimum efficiently.
• The student could explore more optimized solutions for the HashSet problem, such as the one in the reference solution, to improve performance.
