Consider the following java code

class Node { int item; Node next;

Node (int item, Node next) { this.item = item; this.item = next; }

Node duplicate () { Node nextduplicated = (next == null) ? null ; next.duplicate (); Node result - new Node (item, nextDuplicated); return result; } } class NodeExt extends Node { NodeExt (int item, Node next){ super (item, next); } Node duplicate (){ Node result = super.duplicate (); return result; } } Public class Driver { public static void main (string{} args){ Node node1 = new Node (1, new NodeEXT (2, new Node (3, new NodeEXT (4, new Node (5, null))))); Node node2 = node1.duplicate (); } }

In the creation of node 2 how often will the duplicate method within NodeExt be called

1) 0

2) 5

3) 2

4) 4

5) 3

5) 3
