Solution: Add Two Numbers

Explore how to add two non-empty linked lists where each list represents a non-negative integer stored in reverse order. Learn to simulate digit-by-digit addition while handling carries, and return the sum as a linked list. Understand the algorithm's time and space complexity to optimize your coding interview solutions.

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 00 itself.

Constraints:

  • The number of nodes in each linked list is in the range [1,100][1, 100].

  • 00 \leq Node.val 9\leq 9 ...
