Strengths:

• The implementation correctly follows the hash set design using chaining.
• The code is clean, readable, and well-commented.
• The time and space complexity analysis is accurate and clearly stated.

Areas for Improvement:

• Consider using a better hash function or dynamic resizing to handle cases where many elements hash to the same bucket, which could degrade performance.
• The array size (1000) is arbitrary; you might want to choose a prime number to reduce collisions.
• The solution could benefit from unit tests to verify edge cases, such as handling duplicate adds or removes of non-existent elements.
