负数也考虑上去了，可。。。
```
#include <bits/stdc++.h>
using namespace std;
long long a[100000];
int main(){
int n;
cin>>n;
for(int i=1;i<=n;i++){
cin>>a[i];
}
for(int i=1;i<=n;i++){
if(a[i]>=0){
int b;
b=a[i]/7;
cout<<a[i]-b<<endl;
}
else{
int k;
for(int j=1;;j++){
a[i]++;
k++;
if(a[i]==0){
break;
}
}
a[i]=a[i]+k;
int b;
b=a[i]/7;
cout<<a[i]-b<<endl;
}
}
return 0;
}
```

```
b=a[i]/7;
```
此行代码明显有误

且此题不需要考虑负数

是数码7，不是7的倍数
