In the implementation of Singly linked list we had an integer variable called size that keeps track of how many elements in the list. Also, we have a reference tail that points to the last node in the list. You are asked to re-implement the concept of singly linked list without using variable size, and without using reference tail. (You need to rewrite the complete class without tail and without count) (JAVA)

1. What are the methods of the main operation of singly linked list that need to be changed? Rewrite them according to this change (only the methods that need to be changed).

2. Will that affect the performance of any one of the main operations( size, isEmpty, first, last, addFirst, addLast, removeFirst, removeLast)? Explain.
