```cpp
#include <bits/stdc++.h>
using namespace std;
int n, n2, a[10010], a2[10010];
int main() {
memset(a,127, sizeof(a));memset(a2, 127, sizeof(a2));
int n;
cin >> n;
for (int i = 0;i <= n - 1; ++i) {
cin >> a[i];
}
sort(a, a + n);
int i = 0, j = 0, sum = 0, w;
for (int k = 1;k < n; ++k) {
w = a[i] < a2[j] ? a[i++] : a2[j++];
w += a[i] < a2[j] ? a[i++] : a2[j++];
a2[n2++] = w;
sum += w;
}
cout << sum;
return 0;
}
```
我之前写的代码跟你的很像啊哈哈，可以参考一下
