Description
Two non-empty linked lists each encode a non-negative integer in reverse digit order, one digit per node. Add the numbers and return the result as a linked list in the same format. Assume neither number has leading zeros except for the number zero itself.
Example 1:
Input: l1 = [2,4,3], l2 = [5,6,4]
Output: [7,0,8]
Explanation: 342 + 465 = 807.
Example 2:
Input: l1 = [0], l2 = [0]
Output: [0]
Example 3:
Input: l1 = [9,9,9,9,9,9,9], l2 = [9,9,9,9]
Output: [8,9,9,9,0,0,0,1]
