Solution: Add Strings
Explore how to add two non-negative integers represented as strings without direct integer conversion or big integer libraries. Understand the step-by-step approach to simulate manual addition digit by digit, managing carry and pointers effectively. This lesson helps you implement and analyze the solution's time and space complexity for string-based arithmetic.

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.
