看样例，第二个循环i只能到2，但是a有7个&&**计数数组**

### AC代码
```cpp
#include<bits/stdc++.h>
using namespace std;
int a[8],b[1001],c[35],d[8];
int x1,x2,x3,x4,x5,x6,x7;
int sum;
int n;
int main(){
cin>>n;
for(int i=1;i<=7;i++)
{
cin>>a[i];c[a[i]]=1;
}
for(int i=1;i<=n;i++){
sum=0;
for(int j=1;j<=7;j++){
cin>>b[j];
if(c[b[j]]==1)
{
sum++;
}
}
if(sum==1) x7++;
if(sum==2) x6++;
if(sum==3) x5++;
if(sum==4) x4++;
if(sum==5) x3++;
if(sum==6) x2++;
if(sum==7) x1++;
}
cout<<x1<<" "<<x2<<" "<<x3<<" "<<x4<<" "<<x5<<" "<<x6<<" "<<x7;
return 0;
}
