代码？？？

```cpp
#include<bits/stdc++.h>
using namespace std;
int a[305];
int main(){
int n;
cin>>n;
for(int i=0;i<n;i++)
cin>>a[i];
long long sum=0;
sort(a,a+n);
int j,k;
sum+=pow(a[n-1],2);
for(j=0,k=n-1;j<k;){
sum+=pow(a[k]-a[j],2);
k--;
sum+=pow(a[k]-a[j],2);
j++;
}
cout<<sum;
return 0;
}
```
感觉我这代码挺简洁

**- 不开long long 见祖宗**
我也是一半AC，后来发现是开小了，long long 解决
