@okkkkkkkkk

• 对于 #4，题目要求保留 6 位有效数字，不是保留小数点后 6 位。
• 对于 #8，用 cout。
• 对于 #13，要向下取整。

@PRO 十分感谢！可是我的#8依然wa掉了。 希望能够再次指教一下！！！

代码如下：

#include <bits/stdc++.h>
using namespace std;
int main() {
    int T;
    double pie=3.141593;
    cin >> T;
    if (T == 1) {
        cout << "I love Luogu!";
    } else if (T == 2) {
        cout << 2 + 4 << " " << 10 - 2 - 4;
    } else if (T == 3) {
        printf("%d\n%d\n%d\n",3,12,2);
    } else if (T == 4) {
        printf("%.3f",(double)500/3);
    } else if (T == 5) {
        cout<<480/32;
    } else if (T == 6) {
        cout<<sqrt(36+81);
    } else if (T == 7) {
        printf("%d\n%d\n%d\n",110,90,0);
    } else if (T == 8) {
        cout<<10*pie<<25*pie<<0.75*pie*125;
    } else if (T == 9) {
        cout<<22;
    } else if (T == 10) {
        cout<<9;
    } else if (T == 11) {
        printf("%.4f",100.0/3);
    } else if (T == 12) {
        cout<<13<<endl<<"R"<<endl;
    } else if (T == 13) {
        double s = 4.0 / 3 * 64 * pie + 4.0 / 3 * 1000 *pie;
        cout<<floor(pow(s,1.0/3));
    } else if (T == 14) {
        cout<<50;
    }
    return 0;
}

@PRO 8题公式感觉不对啊狗头

@YJXYDWZ 我好像来玩了
