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]
|
||
Explanation: The array represents the integer 123.
|
||
Incrementing by one gives 123 + 1 = 124.
|
||
Thus, the result should be [1,2,4].
|
||
|
||
|
||
Example 2:
|
||
|
||
|
||
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].
|
||
|
||
|
||
Example 3:
|
||
|
||
|
||
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 <= 100
|
||
0 <= digits[i] <= 9
|
||
digits does not contain any leading 0's.
