仅供参考
```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){ //典型的贪心，每一次都只合并所花力气最小的两堆果子！
int a[10000], n, sum = 0;
cin >> n;
for (int i = 1; i <= n; i++){
cin >> a[i];
}
sort(a + 1, a + n + 1); //初始排序
for (;;){
int j = 1;
if (j == n)
break;
else{
a[j] += a[j + 1];
sum += a[j];
for (int i = j + 1; i < n; i++){ //将第一堆后面的前移一个位置，去掉最后一堆
a[i] = a[i + 1];
}
n--;
for (int i = j; i < n; i++){ //把果子堆重新再从小到大排序继续循环直至跳出！
if (a[i] > a[i + 1])
swap(a[i], a[i + 1]);
}
}
}
cout << sum << endl;
return 0;
}
