80分，1，5测试点没过

根据题意模拟即可，求关~

#include<bits/stdc++.h>
using namespace std;
int main(){
    long long x;
    char a,b;
    cin>>x;
    cin>>a>>b;
    if(a=='B'&&b!='C')cout<<x/10*8;
    else if(a!='C'&&b=='B')cout<<x/10*8;
    else if(a=='C'&&b!='B')cout<<x/10*7;
    else if(a!='B'&&b=='C')cout<<x/10*7;
    else if(a=='B'&&b=='C')cout<<x/10*6;
    else if(a=='C'&&b=='B')cout<<x/10*6;
    else cout<<x;
    return 0;
}

且你判断的情况不全，可以再试着改一改~~

@zhanghengrui0502 已关（爱你呦）

@Chen_zi_long 求互关

#include<bits/stdc++.h>
#define int long long
#define double long double
#define endl '\n'
#define ios ios::sync_with_stdio(false),cin.tie(0),cout.tie(0)
using namespace std;
int x;
char a,b;
signed main(){
    ios;
    cin>>x>>a>>b;
    if(a=='A'&&b=='B'||a=='B'&&b=='A')cout<<x/10*8<<endl;
    else if(a=='A'&&b=='C'||a=='C'&&b=='A')cout<<x/10*7<<endl;
    else if(a!=b)cout<<x/10*6<<endl;
    else if(a=='A')cout<<x<<endl;
    else if(a=='B')cout<<x/10*8<<endl;
    else cout<<x/10*7<<endl;
    return 0;
}

怎么都是直接判断的呀？

AC代码

#include<bits/stdc++.h>
using namespace std;
long long n;
char a[3];
bool b,c; 
int main()
{
    cin>>n;
    for(int i=1;i<=2;i++){
    cin>>a[i];
    if(a[i]=='B')b = 1;
    if(a[i]=='C')c = 1;
    }
    if(!b&&!c)cout<<n;
    else if(b&&!c)cout<<n/10*8;
    else if(c&&!b)cout<<n/10*7;
    else cout<<n/10*6;
    return 0;
}

@zhanghengrui0502谢谢 让我AC 你那个n/10乘8我一开始写的是n*8
