Solution in C# (judge verdict: Accepted)

using System;

class Program
{
    static void Main()
    {
        Calc c = new Calc();
        int x = int.Parse(Console.ReadLine());
        Console.WriteLine(c.Multiple(x));

    }
}

class Calc
{
    public int Multiple(int x)
    {
        if (x >= 1 && x <= 100)
            return x * x * x;
        else
            return 0;
    }
