这样就行啦

#include<iostream>
using namespace std;

int main(){
    char a,b;
    long long int x;
    cin>>x>>a>>b;
    if((a=='B'&&b=='C')||(b=='B'&&a=='C')){
        cout<<x*6/10;
    }else if((a=='B'&&b=='A')||(b=='B'&&a=='A')||(b=='B'&&a=='B')){
        cout<<x*8/10;
    }else if((a=='A'&&b=='C')||(b=='A'&&a=='C')||(b=='C'&&a=='C')){
        cout<<x*7/10;
    }else{
        cout<<x;
    }
    return 0;
}
