Solution: Add Strings
Discover how to add two non-negative integers represented as strings by simulating manual digit-by-digit addition. Learn to handle carries and combine digits without converting inputs directly to integers. This lesson teaches a fundamental approach useful in coding interviews where built-in large integer handling is not allowed.

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.
