Sicily 1817. 校歌手大奖赛

它题目要求用类实现, 那我就用了个类实现了. 好简单

不多说

// Problem#: 1817
// Author#: Reid Chan

#include <iostream>
#include <iomanip>
#include <stdio.h>

using namespace std;

class Competitor {
private:
    double sum;
    double cnt;
    double max;
    double min;
public:
    Competitor() {
        sum = 0;
        cnt = 0;
        max = -1;
        min = 101;
    }
    double average() {
        return (sum - max - min) / (cnt - 2);
    }
    void set(int s) {
        sum += s;
        ++cnt;
        if (s > max) {
            max = s;
        }
        if (s < min) {
            min = s;
        }
    }
};

int main() {
    int t;
    cin >> t;
    while (t--) {
        int n, m;
        scanf("%d%d", &n, &m);
        Competitor *cpt = new Competitor [m];
        for (int i = 0; i < n; ++i) {
            int score;
            for (int j = 0; j < m; ++j) {
                scanf("%d", &score);
                cpt[j].set(score);
            }
        }
        for (int j = 0; j < m; ++j) {
//          cout << fixed << setprecision(2) << cpt[j].average() << endl;
            printf("%.2f\n", cpt[j].average());
        }
    }
    return 0;
}
