Available question text
Given two non-negative integers as decimal strings, return their sum as a string by simulating digit-by-digit addition from the least significant digits with carry (no integer conversion or big-integer libraries allowed). Inputs can be large (length up to 10^4), so the solution must handle arbitrary-length strings.
