Solution: Plus One
Explore how to solve the 'Plus One' problem by incrementing a non-negative integer represented as an array of digits. Understand how to manage carries across digits, handle edge cases where all digits are nine, and implement a solution with O(N) complexity. This lesson improves your ability to tackle similar arithmetic and array manipulation challenges in coding interviews.
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.
