Problem: Add Two Numbers

Medium

30 min

Understand how to add two numbers represented by reversed linked lists, where each node contains a single digit. This lesson guides you through solving the problem by implementing addition and managing carries, helping you develop a practical approach to linked list manipulation in coding interviews.

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.
