或者你去重的方法不行

```
#include<cstdio>
#include<queue>
#include<algorithm>
using namespace std;
int n,Ans;
int a[100000];
int main()
{
scanf("%d",&n);
for(int i=1;i<=n;++i)
{
scanf("%d",&a[i]);
if(a[i]==a[i-1])
{
--i;
--n;
}
}
for(int i=2;i<n;++i)
{
if(a[i]<a[i-1] && a[i]<a[i+1]) ++Ans;
}
printf("%d",Ans);
return 0;
}
```
