You have the following doubly linked list node:

class Node{

int data;

Node next;

Node prev;

}

Write a recursive method that will perform a special type of summation on a doubly linked list L of

length n :

You have the following doubly linked list node: class Node{ int

L (i ) indicates the data value in the i th Node of the linked list L . Location i starts from zero.

Example 1: If the linked list contains f 10, 2, 3, 4, 5g , the method must do the following summation

10 5 + 2 4 + 3 3 = 67

Example 2: If the linked list contains f 10, 2, 3, 4g , the method must do the following summation

10 4 + 2 3 = 46

The method header is provided below.

public static int specialSum(Node head, Node tail){

}

(n-1)/2 ) LG) L(n-1-1 2-0
