Solution: Add Strings
Understand how to simulate elementary addition of two string-represented numbers by iterating from the least significant digit with carry management. This lesson teaches a step-by-step approach to sum large numeric strings without built-in integer conversions, focusing on pointer traversal and efficient string manipulation.

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.
