用递归函数编写计算阶乘的代码

import java.util.Scanner;/*NowJava.com 提 供*/


public class Main {


    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        System.out.println(factorial(input.nextInt()));

        input.close();


    }


    static int factorial(int n) {

        // your code here

    }

    

}
