Plus One
You receive 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 provide the resulting array of digits.
Input: digits = [1,2,3]
Output: [1,2,4]
Explanation: The array represents the integer 123.
Incrementing by one gives 123 + 1 = 124.
Thus, the result should be [1,2,4].
Input: digits = [4,3,2,1]
Output: [4,3,2,2]
Explanation: The array represents the integer 4321.
Incrementing by one gives 4321 + 1 = 4322.
Thus, the result should be [4,3,2,2].
Input: digits = [9]
Output: [1,0]
Explanation: The array represents the integer 9.
Incrementing by one gives 9 + 1 = 10.
Thus, the result should be [1,0].
Constraints
1 <= digits.length <= 1000 <= digits[i] <= 9digitsdoes not contain any leading0's.
