Solution: Add Strings
Explore how to implement addition of two non-negative integers represented as strings without converting them directly to integer types. Learn a step-by-step algorithm that simulates manual addition by processing digits from right to left while managing carry-over, enabling efficient handling of large numeric strings within coding 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.
