Example 1:

Input: l1 = [2,4,3], l2 = [5,6,4]

Output: [7,0,8]

Explanation: Given numbers are 342 (from [2,4,3]) and 465 (from [5,6,4]). Adding them: 342 + 465 = 807. In reverse order, this is [7,0,8].

Example 2:

Input: l1 = [0], l2 = [0]

Output: [0]

Explanation: Given numbers are 0 and 0. Adding them: 0 + 0 = 0. In reverse order, this is [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]

Explanation: Given numbers are 9,999,999 and 9,999. Adding them: 9,999,999 + 9,999 = 10,009,998. In reverse order, this is [8,9,9,9,0,0,0,1].

Constraints:

Time Complexity
