题目里说k好像是个字符串

k是字符串，不是字符
```cpp
#include<bits/stdc++.h>
using namespace std;
string a[114514];
string key;//题目中的k
int n;
bool judge(string a,string key)
{
if(a.length()<key.length()) return false;
for(int i = 0;i<key.length();i++)
{
if(a[i]!=key[i]) return false;
}
return true;
}
int main()
{
cin>>n;
for(int i = 0;i<n;i++)
{
cin>>a[i];
}
cin>>key;
sort(a,a+n);
for(int i = 0;i<n;i++)
{
if(judge(a[i],key))
{
cout<<a[i]<<endl;
}
}
return 0;
}
```
