题解 | #求小球落地5次后所经历的路程和第5次反弹的高度#

#include <cstdio>
#include <iostream>
using namespace std;

int main() {
    double height;
    cin >> height;

    double bounce = 0;
    double count = 0;
    double all = 0;

    while(count < 5){
        all += height;
        bounce = height/2;
        all += bounce;
        height = bounce;
        count++;
    }
    printf("%.6lf\n", all-height);
    printf("%.6lf", height);
}
// 64 位输出请用 printf("%lld")
