AC Code 仅供参考：
```c
#include <bits/stdc++.h>
using namespace std;
int main()
{
int y, s = 0, m, x;
for (int i = 1; i <= 12; i++)
{
cin >> y;
s = 300 - y + s;
if (s < 0)
{
cout << -i;
break;
}
if (s >= 100)
{
x = s % 100;
m += s - x;
s = x;
}
}
if (s >= 0)
cout << s + m * 1.2;
return 0;
}
```
本人不太擅长纠错误或者写注释啊。。。
将就着看吧。。。
求个关

就是问关注有啥用吗
```
#include<cstdio>
using namespace std;
int m=0,j=0,t,y;//j是津津手里的钱，m是存在妈妈里的钱
int main()
{
for(int i=1;i<=12;i++)
{
scjnf("%d",&y);
t=j+300-y;
j=t%100;
m=m+t/100*100;
if(t<0)
{
printf("-%d",i);
return 0;
}
}
printf("%.0lf",m*1.2+j);
return 0;
}
