    static int Factorial(int n)

        if (n == 1) return 1;

        Console.Write("Enter number of vowels: ");
        int vowels = int.Parse(Console.ReadLine());

        Console.Write("Enter number of consonants: ");
        int consonants = int.Parse(Console.ReadLine());

        Console.WriteLine(

            Factorial(consonants)
