是的没错 $TAT$ 但我总觉得题目说是月初做这个操作，题目没说是花掉开销后的整百的钱，然后就假装非常追求严谨的试图说题目不对

@[doris_xyb](/user/731828) 啊是我没看懂，紫衫

@[iterator_traits](/user/72922) 额，其实这样理解应该是对的，我刚看题解都是这个意思，但我老是想批评题目（也就是因为题目很烦吧）

```
#include<iostream>
using namespace std;
int main()
{
int x=0,n,m=0,c=0;
for(int x=1;x<=12;x++)
{
cin>>n;
m=m+300-n;
c=c+m/100;
m=m%100;
if(m<0)
{
cout<<-x;
return 0;
}
}
cout<<m+100*c*1.2;
return 0;
}
```
