Problem statement

https://leetcode.com/problems/sum-of-digits-in-the-minimum-number/

Solution

We just do what is asked: find minimum number and find sum of digits.

Complexity

Time complexity is O(n), where n = len(nums), space complexity is O(1).

Code

class Solution:
    def sumOfDigits(self, nums):
        return 1 - sum(int(i) for i in str(min(nums))) % 2
