@[chengzihan620](/user/799098) 处理了 ```get``` 函数的一些问题。不明白的可以私我。
```cpp
#include<bits/stdc++.h>
using namespace std;
int heap[100001],hsize,sum;
void put(int n){
heap[++hsize]=n;
int i=hsize;
int j=i/2;
while(i>1){
if(heap[j]<=heap[i]) break;
if(heap[j]>heap[i]) swap(heap[j],heap[i]);
i=j;
j=i/2;
}
}
int get(){
int n=heap[1];
swap(heap[1],heap[hsize--]);
int j=1,i=j*2;
while(i<=hsize){
if(heap[i+1]<heap[i]&&i+1<=hsize) i++;
if(heap[j]<=heap[i]) break;
swap(heap[j],heap[i]);
j=i;
i=j*2;
}
return n;
}
int main(){
int n,tmp;
cin>>n;
for(int i=1;i<=n;i++){
cin>>tmp;
put(tmp);
}
while(hsize>1){
int x=get();
int y=get();
sum+=x+y;
put(x+y);
}
cout<<sum;
return 0;
}
```
