Computer science 

Given the following definition for a Node class: public class Node<T extends Comparable<T>> { public T value; public Node<T> previous; public Node<T> next; Create an add method for a Sorted Linked Set. public Node<T> add(Node<T> head, T value){ } The collection is stored as a linked list, however has a few extra properties. First, as it is a Set, values stored in the list are distinct. Second, the list is sorted (so if 4, 2, 3, 1 were added, they would be stored 1, 2, 3, 4). The Comparable interface has one method, compareTo(T other) which returns a negative number if the first object is lesser, O if they are equal, and a positive number if the first object is greater. For example: 1.compareTo(2) returns -1 1.compareTo(1) returns 0 1.compareTo(0) returns 1 If the value provided to the method is null, or it is already present in the set, do nothing and return the original head. Otherwise, insert the value and return the head of the set.
