JAVA递归
n的阶乘
http://www.nowcoder.com/questionTerminal/97be22ee50b14cccad2787998ca628c8
注意递归函数的返回值要改成long不然在13以后会溢出
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
while(sc.hasNext()){
int n=sc.nextInt();
System.out.println(jieChen(n));
}
}
public static long jieChen(int n){
return n>1?n*jieChen(n-1):1;
}
}
