拿去用吧KID!!!

#include <iostream>
using namespace std;
int main (){
int n;
int sum=0;
int x[10001];
cin >> n;
for(int i=0;i<=n;i++){
cin >> x[i];
}for(int i=0;i<=n;i++){
if(x[i]>70&&x[i]%70==0){
sum=sum+x[i]/70;
}else{
if(x[i]<=70){
sum=sum+1;
}else{
if(x[i]>70&&x[i]%70!=0){
sum=sum+x[i]/70+1;
}
}
}
}
cout << sum*0.1-0.1;
return 0;
}
