救救我。。```cpp #include <bits/stdc++.h> using namespace std;

int main() { int j = 0, m = 0, cost = 0, sum = 0,ans=0; for (int i = 1; i <= 12; i++) {

	cin >> cost;
	j = j + 300 - cost;
	if (j < 0) {
		ans=-i;
	}
	while (j >= 100) {
		j -= 100;
		m += 100;
	}


}
    if(ans==0)

{

sum = m * 1.2 + j;
cout << sum;

} else cout<<ans<<endl; return 0;

}
