Add two numbers is well known problem with multiple variations. In all cases we are asked to add two numbers digit by digit instead of a normal 'plus' operation. We'll discuss common variations and will solve the following one.
A linked-list variation of the task from Leetcode:
"You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list."
