Problem: Add Two Numbers

Medium

30 min

Understand how to add two non-negative integers represented as reversed linked lists. Learn to manipulate linked list nodes to perform addition and return the sum in the same structure, preparing you for similar coding interview challenges.

Statement

You are given two non-empty linked lists, where each list represents a non-negative integer.
The digits are stored in reverse order, and each node contains exactly one digit.

Your task is to add the two integers and return the result as a linked list, also stored in reverse order.

You may assume that neither number has leading zeros, except the number $0$ itself.

Constraints:

The number of nodes in each linked list is in the range $[1, 100]$ .
$0 \leq$ Node.val $\leq 9$
It is guaranteed that the list represents a number that does not have leading zeros.
