Solution: Add Strings
Explore a method to add two non-negative integers given as strings without converting them directly to numeric types. Understand how to simulate manual addition digit-by-digit, handling carry and pointers for efficient string traversal. This lesson helps you master string-based arithmetic useful in coding interviews.

Statement
Given two non-negative integers, num1 and num2, represented as strings, return the sum of num1 and num2 as a string.
You must not use any built-in library for handling large integers (such as BigInteger) or directly convert the inputs to integers.
