我也wa on test1
数据下载下来是对的
不理解
```
#include<bits/stdc++.h>
using namespace std;
set<string>qwq;
int main(){
int a, b;
int ans = 0;
cin >> a >> b;
for(int i = 0; i <= a; i++){
string s;
getline(cin, s);
qwq.insert(s);
}
for (int j = 0; j < b; j++){
string s;
getline(cin, s);
if (qwq.find(s)!= qwq.end()) ans++;
}
cout << ans<<endl;
return 0;
}
```

test1好像洛谷上最后一个字符串多了一个 `\r`
