Solution: Add Strings
Explore how to add two large numbers represented as strings without converting them directly to integers. Learn to simulate manual addition by processing digits from right to left, managing carries, and forming the resulting sum string efficiently. Understand the time and space complexity of this approach and apply this essential pattern to solve similar coding interview problems.

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.
