鸡尾酒疗法效果比较：C++代码实现

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

int main() {
    int n;
    cin >> n;
    vector<int> total(n), effective(n);
    for (int i = 0; i < n; i++) {

    }

    int cocktail_total = total[0];
    int cocktail_effective = effective[0];

        int current_effective = effective[i];

        double cocktail_rate = (double)cocktail_effective / cocktail_total;
