https://leetcode.com/problems/sign-of-the-product-of-an-array/

There is a function signFunc(x) that returns:
1 if x is positive.
-1 if x is negative.
0 if x is equal to 0.
You are given an integer array nums. Let product be the product of all values in the array nums.
Return signFunc(product).

class Solution:
    def arraySign(self, nums: List[int]) -> int:
        sign = 1
        for num in nums:
            if num == 0:
                return 0
            if num < 0:
                sign = -sign
        return sign
