Solution: Add Strings
Understand how to simulate manual addition of two string-represented numbers by processing digits from right to left. Learn to handle carry operations and manage character to integer conversions without relying on built-in large number libraries. This lesson guides you through implementing an efficient algorithm to sum large numbers represented as strings, maintaining optimal 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.
