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 <iostream>
using namespace std;

int main() {
    int height;
    cin >> height;
    double temp = (double)height;
    double sum = (double)height; //总里程
    double half; //最后一次
    for (int i = 1; i < 5; i++) {
        half = (double)temp / 2;
        sum += half * 2; //落地
        temp = half;

    }

    cout << sum << endl;
    cout << half / 2 << endl;
}
// 64 位输出请用 printf("%lld")
