交这份代码
```
#include <bits/stdc++.h>
using namespace std;
void readToken(string &s){//快读
char c;
while((c=getchar())!='\n'&&c!='\r')
s+=c;
return;
}
void do_everything(string a,string b){
if(a.size()==0)return;
int middle=a.find(b[b.size()-1]);
cout<<a[middle];
do_everything(a.substr(0,middle),b.substr(0,middle));
do_everything(a.substr(middle+1),b.substr(middle,b.size()-middle-1));
return;
}
int main(){
string s,t;
readToken(s);readToken(t);
do_everything(s,t);
return 0;
}
```

奇怪，直接cin就A了

string最好不要用什么快读~~（cin其实也不慢的了）~~
