Implement Hash Set (design-1.py)

Strengths:

• Clean, well-documented code with clear comments explaining the approach
• Correct handling of the edge case for bucket 0 (needs secondaryBucket+1 slots)
• Proper null-checking before accessing nested structures
• Good use of descriptive variable names (hashfunc1, hashfunc2, etc.)

Areas for Improvement:

• The space complexity explanation in comments is confusing. It should simply state O(n) where n is the number of keys, or O(1) per operation for amortized space.
• Consider using more Pythonic variable names (e.g., self.primary_bucket instead of camelCase)

VERDICT: PASS

Implement Min Stack

1. Wrong Problem: The student solved "Design HashSet" (LeetCode 705) instead of "Min Stack" (LeetCode 155). This is a fundamental mismatch.

2. Missing Required Functionality: The solution doesn't implement any of the required MinStack methods:

   • push(int val) - not implemented
   • pop() - not implemented
   • top() - not implemented
   • getMin() - not implemented

3. Correctness: The solution is incorrect for the given problem as it solves a different problem entirely.

4. Time/Space Complexity: The analysis is for the wrong problem (HashSet operations), not the MinStack problem.

5. Recommendation: The student needs to:

   • Re-read the problem statement carefully
   • Implement a stack-based solution with two stacks (main stack + min stack)
   • Ensure all four required methods are implemented
   • Provide accurate complexity analysis for the MinStack operations

VERDICT: NEEDS_IMPROVEMENT
