• solved Disgn Hashmap
• solved Implement Queue using stacks

Strengths:

• The student has a good understanding of the data structures and their implementations.
• The code is well-commented and easy to follow.
• The use of helper methods (hashFunc, find) in the HashMap implementation shows good modular design.

Areas for Improvement:

• In the Queue implementation, the pop method could call peek to avoid duplicating the logic for transferring elements from inStack to outStack. This would make the code more maintainable.
• The comments in the Queue implementation could be more detailed, especially explaining why the two-stack approach works for queue operations.
• The time complexity analysis for the Queue could mention the amortized nature of the operations, as the worst-case time complexity for pop and peek is O(n) when outStack is empty.
