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.

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

    'input': { 
        'l1': [2, 4, 3],
        'l2': [5, 6, 4]
    'output': [7, 0, 8]
