Quick Overview

This question evaluates a candidate's ability to manipulate arrays and manage carry propagation in a digit-by-digit arithmetic simulation. It is a classic coding interview problem testing edge-case handling, such as trailing nines and array resizing, without relying on built-in big-integer types. The task assesses practical, hands-on array manipulation skill at a foundational algorithmic level.
