Problem 1:(https://leetcode.com/problems/design-hashset/)

Problem 2:(https://leetcode.com/problems/min-stack/)

[super30admin]

Strengths:

• Good implementation of double hashing in MyHashSet, correctly handling edge cases.
• Clear and concise comments explaining the approach.
• Proper separation of concerns in both solutions.
• Correct use of helper methods for hashing in MyHashSet.

Areas for Improvement:

• In MyHashSet, the variable names buckets and bucketItems could be more descriptive (e.g., primaryBuckets and secondaryBuckets to match the reference solution).
• The MinStack implementation pre-allocates large arrays (10000 elements), which might be wasteful. Consider using dynamic data structures like ArrayList or resizing arrays when needed.
• The comments in Problem1.java mention "space - O(n)" which is technically correct but could be more precise (O(1) per operation amortized).
• Missing newline at the end of both files (minor style issue).

Strengths:

• Good understanding and implementation of double hashing for HashSet.
• Clear comments explaining the approach.
• Proper handling of edge cases.
• Correct time and space complexity analysis.

Areas for Improvement:

• For MinStack, consider using dynamic data structures like ArrayList instead of fixed-size arrays to handle larger inputs more flexibly.
• Add more detailed comments in the MinStack implementation to explain the logic behind maintaining the minStack.
• Ensure consistent formatting (e.g., spacing around operators and braces) throughout the code.
• Consider adding input validation or bounds checking where applicable.
