不同getline换cin试一下

过了，getline可能会多读入，最好别用
~~可以给个关注吗~~

```
#include<iostream>
#include<string>
using namespace std;
void getstring(string ins,string pres)
{
int i;
char ch;
if (pres.length()==1 || pres.length()==0 )
{
cout<<pres[0];
return;
}
ch=pres[0];
for (i=0;i<ins.length();i++)
if (ins[i]==ch) break;
if (i>0) getstring(ins.substr(0,i),pres.substr(1,i));
if (i<ins.length()-1) getstring(ins.substr(i+1),pres.substr(i+1));
cout<<ch;
}
int main()
{
int i;
string ins,pres,posts;
cin>>ins>>pres;
getstring(ins,pres);
cout<<endl;
return 0;
}
