STL大法好
```cpp
#include<iostream>
#include<cstdio>
#include<string>
#include<map>
#include<algorithm>
using namespace std;
int n;
map<string,int> m;
string s;
int main()
{
scanf("%d",&n);
while (n--)
{
cin>>s;
sort(s.begin(),s.end());
m[s];
}
printf("%d\n",m.size());
return 0;
}
和上面的对比…………

```cpp
#include <iostream>
#include <string>
#include <algorithm>
using namespace std;
string s[10005] = {};
int main()
{
int n;
cin >> n;
getline(cin, s[1]);
for(int i = 1; i <= n; i++)
{
getline(cin, s[i]);
sort(s[i].begin(), s[i].end());
}
sort(s+1, s+n+1);
int cnt = 1;
for(int i = 2; i <= n; i++)
{
if(s[i] != s[i - 1])
{
cnt++;
}
}
cout << cnt << endl;
return 0;
}
