Solution: Add Strings
Understand how to add two non-negative integers represented as strings by simulating manual addition, handling carries and digits without built-in integer conversions. Explore an efficient algorithm that processes digits from right to left, enabling you to solve coding interview problems involving large numbers without direct numeric conversion.

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.
