"""
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].

class Solution:
def plusOne(self, digits: List[int]) -> List[int]:
number_str = ""
for _, v in enumerate(digits):
number_str = number_str + str(v)
number_str = str(int(number_str) + 1)
return([int(x) for x in number_str])
