Feedback on second submission

[Anisha7]

Good job on completing the second coding challenge. Here's some feedback to improve your code further:

• Optimizing your linked stack is required for full credit. The top of your stack should be the head of your linked list for all O(1) operations.
• You should be able to access the set’s size property without having to call the hash table’s size. Implement it to update the set class’s size property each time an element is added or removed. Or use @Property method (Python @property: How to Use it and Why? - Programiz) to utilize the hash table’s size property but be able to access it as set.size
