In this video, we solve LeetCode Problem 2 – Add Two Numbers.
The problem gives two non-empty linked lists representing two non-negative integers where digits are stored in reverse order. Each node contains a single digit, and we need to add the two numbers and return the result as a linked list.
We simulate the same process as manual addition, digit by digit, while maintaining a carry. This is a classic Linked List + Simulation problem and is very common in coding interviews.
