Solution: Add Strings
Explore the approach to add two large non-negative integers represented as strings without using built-in integer conversions. Learn to simulate manual addition by processing digits from right to left while managing carry values. This lesson helps you understand how to handle large number addition programmatically in C++ with efficient time and space complexity.

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.
