题目叫我用我偏不用](https://www.acgo.cn/problemset/423/explanation)

#include <iostream>
using namespace std;

int main(){
    int n,a;
    double count;
    cin >> n;
    for(int i = 0;i < n;i++){
        cin >> a;
        if(a <= 70){
            count += 0.1;
        }else{
            while(a>70){
                count+=0.1;
                a-=70;
            }
            count+=0.1;
        }
    }
    cout << count;
    return 0;
}
