No description provided.

Implemented a MyHashSet class using a two-dimensional array to store elements. The class includes methods to add, remove, and check for the existence of elements with O(1) time and space complexity.
Implement MinStack with push, pop, top, and getMin methods.

  1. MyHashSet:

    • The solution is well-implemented and matches the reference solution closely.
    • The comments are helpful, but the method names hash1 and hash2 could be more descriptive (e.g., getPrimaryHash and getSecondaryHash as in the reference solution).
    • The use of hardcoded values (1000) could be replaced with the class variables primaryBuckets and secondaryBuckets for better maintainability.
  2. MinStack:

    • The solution is correct and efficient.
    • The initial push of Integer.MAX_VALUE to minStack is a good practice to handle the empty stack case.
    • The variable min could be renamed to something more descriptive like currentMin to avoid confusion with the method getMin.
  3. General:

    • The student has provided clear and concise comments, which is excellent.
    • The code follows good practices, but minor improvements in variable naming could enhance readability further.
