你可以用if()else if()else语句呀, 这种题尽量别用switch()
```c
#include<bits/stdc++.h>
using namespace std;
int a[3];
void v(char a2){
if(a2=='A') cout<<a[0];
else if(a2=='B') cout<<a[1];
else cout<<a[2];
cout<<" ";
}
char a1, b, c;
int main(){
cin>>a[0]>>a[1]>>a[2];
sort(a, a+3);
cin>>a1>>b>>c;
v(a1);
v(b);
v(c);
}
```
