Python

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

Go

func arraySign(nums []int) int {
    result := 1
    for _, num := range nums {
        if (num == 0) {
            return 0

        if (num < 0) {
            result = -result
        }
    }
    return result
}

Rust

impl Solution {
