Solution: Plus One
Explore the process of adding one to a number stored as a digit array by applying carry rules from right to left. Understand how to handle cases of digit overflow, when all digits are nines, and learn the step-by-step algorithm that updates the array or creates a new one when necessary. This lesson explains the logic behind the arithmetic increment and discusses time and space complexity considerations.
We'll cover the following...
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.
