Understand the problem
Restate the problem precisely. Interviewers reward candidates who pause, define the contract, and name the guarantees before coding.
Problem statement
You are given a large integer represented as an integer array `digits`, where each `digits[i]` is the *i*-th digit of the integer. The digits are ordered from most significant to least significant in left-to-right order. The large integer does not contain any leading 0's. Increment the large integer by one and return the resulting array of digits.
Example
digits = [1, 2, 3] → [1, 2, 4]
Constraints
1 ≤ digits.length ≤ 100 · 0 ≤ digits[i] ≤ 9 · digits has no leading zeros except for the value 0
