Consider the following code snippet for adding elements to a Linked List: public void add(int data) { LinkedList newNode = new LinkedList(data); if (this.node == null) // if the LL is empty node = newNode; else { // if the LL is !empty LinkedList tempNode = node; while (tempNode.getNode() != null) tempNode tempNode.getNode(); tempNode.setNode(newNode); } How would you modify this method to add element at a specific index: public void add(int data, int index) { //method body 0 } In other words, what should be the method body in the second diagram?
