Strengths:

1. The HashSet implementation correctly uses chaining to handle collisions, which is a good approach.
2. The MinStack implementation is efficient and correctly maintains the minimum values in a separate stack.
3. The code is well-structured and readable, with clear method names and comments.

Areas for Improvement:

1. For the HashSet, the choice of 1000 as the size is arbitrary. It would be better to choose a prime number to reduce the likelihood of collisions, especially since the keys can be up to 10^6.
2. The MinStack implementation could be optimized further by only pushing to the min_stack when the new value is less than or equal to the current minimum, rather than always pushing the current minimum. This would reduce the space usage in cases where the same minimum is repeated multiple times.
3. Adding more comments or docstrings to explain the design choices and the expected behavior of the methods would improve the code's maintainability.
