1. You are given a linked list with N nodes.
2. The non-empty singly linked list represents a non-negative integer. Each node of the list contains a digit between 0 - 9.
You may assume that the integer do not contain any leading zero, except the number 0 itself.
The digits are stored such that the most significant digit is at the head of the list.
3. You have to write a function that adds one to the number represented by the list and stores the result in the linked list.
4. display is a utility function which displays the contents of Linked List, feel free to use it for debugging purposes.
5. main takes input from the users and creates the Linked List. You can use display to know its contents.
6. This is a functional problem.
7. You should code only the plusOne function. It takes as input the head of the linked list. It should return the head of the plus one linked list.
8. Don't change the code of Node, main and display.Input Format
First line takes N, the number of elements in the list. Second line takes input N space separated numbers reperesenting elements of the linked list. Input is handled for you.
Output Format
Linked List with one added to it. Output is handled for you.
Constraints
1 <= N <= 300
