看代码

#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;
}

你能加团or关注吗？

呵呵

竟然是打表

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;
}
