@[New_hope](/user/416242) 用啥unique啊，string可以直接按字典序sort，~~还有就是，这什么鬼码风~~
```cpp
#include<bits/stdc++.h>
using namespace std;
string r[10005];
int main(){
int n;
int ans=1;
cin>>n;
for(int i=1;i<=n;i++){
string s;
cin>>s;
sort(s.begin(),s.end());
r[i]=s;
}
sort(r+1, r+n+1);
for(int i=2; i<=n; i++)
{
if(r[i]!=r[i-1]) ans++;
}
cout<<ans;
return 0;
}
```

@[New_hope](/user/416242) `unique` 是把相邻的元素去重。不排序怎么保证重复元素相邻呢？
