C语言训练-求函数值 （Java代码）递归

参考代码:

import java.util.Scanner;

public class Main1137 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int x = sc.nextInt();

System.out.println(f(x));

}

private static int f(int x) {

if (x == 1)

return 10;

else

return f(x - 1) + 2;

}

}
