        int n,
        fact = 1;
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter number of series=");
        n = sc.nextInt();
        for (int i = 1; i <= n; i++)
        {
            fact = fact * i;
        }
        System.out.println("Factorial=" + fact);
    }
}
