1085. Sum of Digits in the Minimum Number

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

class Solution {
public:
    int sumOfDigits(vector<int>& nums) {
        int mi = *min_element(begin(nums), end(nums));
        int res = 0;
        while(mi) {
            res += mi % 10;
            mi /= 10;
        }
        return !(res & 1);
    }
};
