```cpp
#include <cstdio>
#include <algorithm>
using namespace std;
struct ${
int s;
int id;
};
$ a[100001];
int n,ans;
int cmp($ p,$ q)
{
return p.s<q.s;
}
int main()
{
scanf ("%d",&n);
for (int i=0;i<n;i++)
scanf("%d",&a[i].s),a[i].id=i;
sort(a,a+n,cmp);
for(int i=0;i<n;i++)
if(a[i].id!=i)
ans++;
printf("%d",ans-1);
}
```
不过好像只有10分
