Hi Veronica, I'm grading this as a red as your Stack implementation doesn't use a LinkedList which we do want you to practice using. We'd also like for you to make an attempt at the comprehension questions.
I'd be happy to regrade when you resubmit.

LinkedList class in your implementation. The reason is that we want you to get more practice using (in addition to implementing) linked lists as they are commonly used in interviews.

✨ Nice work! Thanks for updating. For the difference between implementing v using. Implementing means to write or implement a function/piece of code yourself. Using means to just call or reuse code that someone else wrote/implemented. Think about when you use functions from a library or imported module or call an API, vs you implementing your own set of functions or your own API.
Let me know what questions you have!
