Create Queue using Stacks (problem-1.py)

Strengths:

• Clean and readable implementation with proper docstrings
• Correct use of the two-stack approach for queue implementation
• Good comment explaining time/space complexity upfront
• Handles edge cases properly (empty queue check in pop)
• Code structure matches the standard solution approach

Areas for minor improvement:

• The comment "Did this code successfully run on Leetcode : YES" is unnecessary for production code
• Could add type hints for better code documentation (e.g., def push(self, x: int) -> None:)

Overall, this is a solid implementation that correctly solves the problem with optimal time and space complexity.

VERDICT: PASS

Implement Hash Map (problem-2.py)

Strengths:

1. Clean implementation following the separate chaining pattern correctly
2. Good use of dummy node to simplify edge case handling
3. Well-structured code with clear comments and docstrings
4. Correctly handles all required operations (put, get, remove)
5. Good variable naming within methods

Areas for Improvement:

1. The size array should be renamed to storage or buckets for clarity
2. Consider adding null checks in the find function for better robustness
3. The hash function could benefit from a secondary hash to reduce collisions
4. The bucket size (10000) could be dynamically chosen based on expected input size

Comparison to Reference:

• The solution is functionally equivalent to the reference solution
• Uses the same approach (separate chaining with linked lists)
• Slightly different bucket size (10000 vs 1000), which is a minor implementation choice

The solution demonstrates solid understanding of hash map implementation and correctly solves the problem.

VERDICT: PASS
