```cpp
while(que.size()>=1)
```
改为
```cpp
while(que.size()>1)
```

可是为什么在本地样例过了，[IDE](https://www.luogu.com.cn/ide)里却没过

给那些各位大佬，把代码改成：
```
#include<iostream>
#include<queue>
using namespace std;
int main(){
priority_queue<int,vector<int>,greater<int> > que;
int n,ans=0;
cin >> n;
for(int i=1;i<=n;i++){
int a;
cin >> a;
que.push(a);
}
while(que.size()>1){
int p=que.top();
que.pop();
int q=que.top();
que.pop();
que.push(p+q);
ans+=q+p;
}
cout << ans;
return 0;
}
```
就AC了。
