```cpp
#include <iostream>
using namespace std;
int main() {
int mon = 0, cun = 0, y[15];
for (int i = 0; i < 12; i++) {
cin >> y[i];
if (mon + 300 < y[i]) {
cout << "-" << i + 1;
return 0;
}
cun += (mon + 300 - y[i]) / 100 * 100;
mon = (mon + 300 - y[i]) % 100;
}
cout << cun * 1.2 + mon;
return 0;
}
```
试试能过不（）
