    typescript/javascript

    console.log((arr.filter(el => el > 0).length/arr.length).toFixed(6)); console.log((arr.filter(el => el < 0).length/arr.length).toFixed(6)); console.log((arr.filter(el => el === 0).length/arr.length).toFixed(6));

    public static void plusMinus(List<int> arr)
    {
        int n = arr.Count;
        if (n > 0 && n <= 100)
        {
            int positives = arr.Count(x => x > 0);
            int negatives = arr.Count(x => x < 0);
            int zeros = arr.Count(x => x == 0);
            
            // Calculate and print ratios with 6 decimal places
            Console.WriteLine("{0:F6}", (decimal)positives / n);
            Console.WriteLine("{0:F6}", (decimal)negatives / n);
            Console.WriteLine("{0:F6}", (decimal)zeros / n);
        }
    }
