Add Two Numbers

MediumLinked-lists
Linked ListMathRecursion

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.

Example :

Example 1:
Input:
l1 = [2,4,3], l2 = [5,6,4]
Output:
[7,0,8]
Explanation:

342 + 465 = 807.

Constraints:

  • The number of nodes in each linked list is in the range [1, 100].
  • 0 <= Node.val <= 9
  • It is guaranteed that the list represents a number that does not have leading zeros.
Solution
Output
