This problem deals with the Array and Linked List implementations of the Unordered List (AUList and LLUList) Use C++ language:

a. Write a class function CopyEarlyList for AUList that duplicates the first N elements of the list and returns it as a new, separate list, in the same order.

b. Explain the major obstacle with implementing the CopyEarlyList function for the LLUList implementation. Note: it has nothing to do with garbage collection. You do not have to implement this code.
