The problem

Given an integer array nums, return 0 if the sum of the digits of the minimum integer in nums is odd, or 1 otherwise.

Example

Input
nums = [34,23,1,24,75,33,54,8]
Output
0
Explanation
The minimal element is 1, and the sum of those digits is 1 which is odd, so the answer is 0.

Python solution

    def sumOfDigits(self, nums: List[int]) -> int:
        x = min(nums)
        s = 0
        while x:
            s += x % 10
            x //= 10
        return s & 1 ^ 1
