@zhenghanyu333 输入BBC的情况你这就不对了吧

emm 要保证a是最小的

还是90分

@zhenghanyu333 你没有考虑输入中没有B和C的情况

else if(b==10)b=1; 

应改为

else if(b==0)b=1;

打错了，应该是 b = 10

俗话说的好：打表大法好

#include<bits/stdc++.h>
using namespace std;
string ask[9]={"AA","AB","AC","BA","BB","BC","CA","CB","CC"};
int ans[9]={10,8,7,8,8,6,7,6,7};
unsigned long long a;
string s;
int check(string x)
{
    for(int i=0;i<=8;i++)
        if(ask[i]==x)
            return ans[i];
}
int main()
{
    cin >> a >> s;
    cout << a/10*check(s);
    return 0;
}
