Solution: Add Two Numbers

Explore how to add two numbers represented by linked lists with digits stored in reverse order. Understand how to simulate digit-by-digit addition while managing carry and building the result as a linked list, a common coding interview pattern. This lesson helps you master linked list manipulation and arithmetic logic needed to solve similar coding challenges efficiently.

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. ...
