    This is my code in Python 3.

    def plusMinus(arr):
    n = len(arr)
    pos = [i for i in arr if i > 0]
    neg = [i for i in arr if i < 0]
    zero = [i for i in arr if i == 0]
    
    print(len(pos) / n)
    print(len(neg) / n)
    print(len(zero) / n)

if __name__ == '__main__':
    n = int(input().strip())
    arr = list(map(int, input().rstrip().split()))
    plusMinus(arr)

    void plusMinus(vector<int> arr) {
	int p = 0, n = 0, z = 0;
	for(int el : arr){
		if(el > 0) 
			p++;
		else if(el < 0) 
			n++;
		else 
			z++;
	}
	double total = arr.size();
	double pr = p / total;
	double nr = n / total;
	double zr = z / total;

	// Set the output to print 6 decimal places
	cout << fixed << setprecision(6);
	// Print each result on a new line
	cout << fixed << setprecision(6);
	cout << pr << "\n" << nr << "\n" << zr;
}

    Rust:

    fn plusMinus(arr: &[i32]) {
    let mut pos: f32 = 0.0;
    let mut neg: f32 = 0.0;
    let mut zer: f32 = 0.0;
    let all = arr.len() as f32;
    
    for &i in arr {
        match i {
            i if i > 0 => pos += 1 as f32,
            i if i < 0 => neg += 1 as f32,
            i => zer += 1 as f32,
        }
    }
    println!("{}", pos / all);
    println!("{}", neg / all);
    println!("{}", zer / all);
}

    JS:

    function plusMinus(arr: number[]): void {
    // Write your code here
    let pos = 0;
    let neg = 0;
    let zer = 0;
    let all = arr.length;
    
    for (const num of arr) {
        switch (true) {
            case num > 0: pos++; break;
            case num < 0: neg++; break;
            default: zer++;
        }
    }
    
    console.log(pos / all);
    console.log(neg / all);
    console.log(zer / all);
}
