@[SIXIANG](/user/298549) 要包iomanip吧

@[封禁用户名239562](/user/239562) 不会吧……这个没有用到iomanip啊，map就够了……

@[不优秀](/user/226919) 什么意思？？？

```cpp
#include <iostream>
#include <map>
using namespace std;
int n;
map <string,int> mp;
int main()
{
string s;
cin>>n;
while(n--)
{
cin>>s;
if(mp[s]++)
cout<<s<<mp[s] - 1<<endl;
else
cout<<"OK"<<endl;
}
return 0;
}
```

@[SIXIANG](/user/298549) 自己看一下，不可能那么麻烦

@[mnesia](/user/115711) 不是我的重点是``` ios::sync_with_stdio(false);```诶，我AC了……
