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!
