@[liuruiqing](/user/1118614) 已更，样例输出良好QwQ
```cpp
#include<bits/stdc++.h>
using namespace std;
stack<char> a;
string p,s;
char ch;
int n;
int main(){
cin>>n;
getline(cin,p);
for(int i=1;i<=n;i++){
cin>>s;
if(s==""){
cout<<"Yes";
break;
}
for(int i=0;i<s.length();i++){
if(!a.empty()&&a.top()=='('&&s[i]==')')
a.pop();
else if(!a.empty()&&a.top()=='['&&s[i]==']')
a.pop();
else
a.push(s[i]);
}
if(a.empty())
cout<<"Yes"<<endl;
else
cout<<"No"<<endl;
while(!a.empty())
a.pop();
}
return 0;
}
```

过不了是因为评测系统的原因吗？

1. for外面getline是什么意思
2. 特判空串里面怎么是break
3. s.size()可能比s.length()更好 @[lucy2012](/user/1252442)
