判断语句就出问题了，输入方式也不对, a、b 不是这么输入的

#include<bits/stdc++.h>
using namespace std;
long long n; char a,b; 
char c[4];int y=10;
int main(){
    scanf("%lld%s",&n,c);
    a=c[0],b=c[1];
    if(a>b) swap(a,b);
    if(a=='A')
        if(b=='A')  
            y=10;
        else if(b=='B')
            y=8;
        else 
            y=7;
    else if(a=='B')
        if(b=='B')
            y=8;
        else
            y=6;
    else
        y=7;
    printf("%lld",n*y/10);
    return 0;
}
