Java写题解的第4天 | #求小球落地5次后所经历的路程和第5次反弹的高度#

解题思路:模拟

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String s = "";
        while ((s = br.readLine()) != null) {
            double height = Double.parseDouble(s);
            // length at 1st get ground
            double length = height + 0.0;
            for (int i = 2; i <= 5; i++) {
                length += height;
                height /= 2;
            }
            System.out.println(length);
            System.out.println(height/2);

        }
        br.close();
    }
}
