15 min

Explore how to increment a non-negative integer represented as an array of digits, understanding key techniques to handle carry-over and update digits. This lesson helps you practice implementing a solution that adds one to the integer array and returns the updated result, enhancing problem-solving skills in math and geometry coding challenges.

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.

Constraints:

$1 \leq$ digits.length $\leq 100$
$0 \leq$ digits[i] $\leq 9$
The digits array does not contain any leading $0$ ’s.
