Add Strings
Understand how to add two non-negative integers given as strings without converting them directly to integers. Learn to implement string-based addition efficiently, a key technique for solving coding problems that involve large number manipulation. This lesson helps you approach string arithmetic challenges commonly asked in technical interviews.

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.
