Question

Given the following definition of the classes Node and SLL as follows:

private static class Node<E> {

private E data;

private Node<E> next;

 

private Node(E dataItem) {

    data = dataItem;

    next = null;

}

 

private Node(E dataItem, Node<E> nodeRef) {

    data = dataItem;

    next = nodeRef;

}

}

public class SLL<E> {

private Node<E> head = null;

private int size = 0;

}

Add the following methods:

  • Add a method in the class SLL to add a new node at the beginning
  • Add a function to display all nodes
  • Add a function to calculate and return the sum of all nodes with even positions (2nd, 4th, etc. nodes)
