If you get WA for the first test in C#

using System;
namespace Timus1104
{
    class Program
    {
        static void Main(string[] args)
        {
            var inputNumber = Console.ReadLine();
            Console.WriteLine("22");
        }
    }
}

just add return value

using System;
namespace Timus1104
{
    class Program
    {
        static int Main(string[] args)
        {
            var inputNumber = Console.ReadLine();
            Console.WriteLine("22");
            return 0;
        }
    }
}
