Solution: Plus One
Explore how to increment a non-negative integer represented as an array of digits by one. Understand the carry mechanism when digits reach nine, and implement an efficient algorithm to handle edge cases, including arrays with all nines. This lesson helps you grasp this common arithmetic pattern used in coding interviews.

Statement
You are given a non-negative integer represented as an integer array, digits, where each element in digits[i] corresponds to a single digit of the integer. The digits are arranged from most significant (left) to least significant (right), and the number has no leading zeros.
Your task is to add one to this integer and return the updated number in the same digit-array format.
