Add Two Numbers question

    R

    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 contain a single digit. Add the two numbers and return it as a linked list.

    You may assume the two numbers do not contain any leading zero, except the number 0 itself.

    Input: (2 -> 4 -> 3) + (5 -> 6 -> 4)
    Output: 7 -> 0 -> 8

    Question:
    How are the numbers exactly adding up?

    Heres a better test case that should make the problem easier to understand:

        l1 = [1,2,3]
        l2 = [4,5,9]
        expected output: [5,7,2,1]
