I have a problem in my code that I can't solve:

I can't run it on a platform's online compiler, which is exactly where I need to use it.

```
using System;

public class help {
    public static void Main() {
        int n = Int32.Parse(Console.ReadLine());
        for (int i = 0; i < n; i++) 
        {
            string[] line = Console.ReadLine().Split(' ');
            double X = double.Parse(line[0]);
            double Y = double.Parse(line[1]);
            if (Y == 0) {
                Console.WriteLine("divisao impossivel");
            } else {
                double divisao = X / Y; // Digite aqui o calculo da divisao
                Console.WriteLine(divisao.ToString("F1"));
            }
        }
    }
}

```

Any ideas?
