/*Another simple Example given by me */
import java.util.Scanner;
public class facto
{

public static void main(String[] args)
{
Scanner scan=new Scanner(System.in);
System.out.println("enter the number");
int number=scan.nextInt();
int factorial=number;
for(int i=(number-1);i>1;i--)
{
factorial=factorial*i;
}
System.out.println("factorial of number is="+factorial);
}
}

/*great dude
here is another demo of factorial */
import java.util.Scanner;
public class facto
{

public static void main(String[] args)
{
Scanner scan=new Scanner(System.in);
System.out.println("enter the number");
int number=scan.nextInt();
int factorial=number;
for(int i=(number-1);i>1;i--)
{
factorial=factorial*i;
}
System.out.println("factorial of number is="+factorial);
}
}
