给你个正解 为啥不看题解

#include <iostream>
using namespace std;
long long x;
char A,B;
int a,b;
int main(){
    cin>>x>>A>>B;
    a=min(A,B);b=max(A,B);
    if(b=='B')x=x/10*8;
    if(a!='B'&&b=='C')x=x/10*7;
    if(a=='B'&&b=='C')x=x/10*6;
    cout<<x;
    return 0;
}

@Kavin_0409 搞错了！

你对的，我少了个输出！

I'm sorry~~~
