The sequence Class Using a Linked List
Discussion 
Your sequence class for this assignment will differ from the your previous sequence in the following ways:

The sequence’s items are now stored on a linked list. The head pointer of the linked list is a private member variable of the sequence class. I suggest that you also have a tail pointer as an additional private member variable of the sequence class. The reason for the tail pointer is explained the LinkedListBag lecture.
Because you are dynamically allocating memory within your sequence class, you will need to define a copy constructor, an assignment operator, and a destructor. You need to pay special attention to the value semantics of your new sequence class – you need not only to make a copy of the linked list, but also need to place the node pointers correctly. Please refer to lectures on LinkedListBag for more detailed discussions on the value semantics.
Start by studying private member variables and functions in sequence3.h


Design a sequence class using a linked list is more complicated than using an array so draw an example linked list when you are writing code for each member function. Always remember to show all the member variables in order to remind you making proper changes of them. Don't forget to place the cursor and the precursor at various locations, head, tail and other places. Also remember that the sequence could be empty, and cursor and/or precursor could be NULL, even when the sequence is NOT empty.
