Problem Statement

You are given two non-empty linked lists that represent two non-negative integers, where each node contains the single digit. The digits are stored in reverse order. Add these two numbers and return the sum as a linked list.

You can assume the numbers do not have leading zeros, except for the number 0 itself.

Examples

Example 1:

  • Input: l1: [1, 2, 3], l2: [4, 5, 6]
  • Expected Output: [5, 7, 9]
