/*

Increment Linked List by 1

This program increments the list by 1. The program takes input with one space and when entered -1 at the end, it stops taking more inputs
For example

Input:
3 1 -1

Output:
3 2

Input2:
9 9 -1

Output2:
1 0 0

Idea is to reverse a LL, made some calculations and reverse it again to obtain the answer.
