Plus One
You are given a large integer represented as an integer array digits, where each digits[i] is the ith 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 1
Input
digits = [1,2,3]Output
[1,2,4]The array represents 123, and adding one gives 124.
Example 2
Input
digits = [4,3,2,1]Output
[4,3,2,2]The array represents the integer 4321.
Incrementing by one gives 4321 + 1 = 4322.
Thus, the result should be [4,3,2,2].
Constraints
- 1 <= digits.length <= 100
- 0 <= digits[i] <= 9
- digits does not contain any leading zeros
