ac代码
```cpp
#include <iostream>
using namespace std;
int tot = 0; //存的
int rest = 0; //手里有的
int a[13];//预算
int i = 1;
int main()
{
for ( i = 1; i <= 12; i++)
{
cin >> a[i];
if (300 + rest - a[i] >= 100)
{
int k = (rest + 300 - a[i]);
rest = k % 100;
tot = tot + k - rest;
}
else if (300 + rest - a[i] < 0)
{
cout << "-" << i;
break;
}
else
{
rest = rest + 300 - a[i];
}
if (i == 12)
{
cout << rest + tot * 1.2;
}
}
return 0;
}
```

帮你改了改，应该是这样：
```cpp
#include <bits/stdc++.h>
using namespace std;
int a[100],sum,m,flag=1;
int main()
{
for(int i=0;i<12;i++)
{
cin>>a[i];
if(flag)
{
sum+=300-a[i];
if(sum<0){
flag=0;
sum=i;
break;
}
m+=sum/100;
sum%=100;
}
}
if(flag) cout<<m*1.2*100+sum;
else cout<<-sum-1;
return 0;
}
```
