import java.util.Scanner;

// 注意类名必须为 Main, 不要有任何 package xxx 信息
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int h = in.nextInt();
        double hDouble = (double) h;
        double l = hDouble;
        int i = 5;
        while (i > 0) {
            hDouble = hDouble / 2;
            if (i > 1) {
                l += hDouble * 2;
            }
            i--;
        }
        System.out.println(l);
        System.out.println(hDouble);
    }
}

太简单了,根据例题的讲解就可以写代码了;
