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;
