Solution: Plus One
Understand how to solve the plus one problem by adding one to an integer array representing a non-negative number. Learn to handle carry operations efficiently by iterating through the digits array from right to left, updating digits based on arithmetic addition rules. This lesson helps you implement a solution with linear time complexity and prepares you for similar math-related coding interview questions.

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.
