        if(s[i+1]=='C'&&s[i+2]=='P'&&s[i+3]=='C')c++;
        sum=max(sum,ans+d+max(p,c));
    }
    cout<<sum<<'\n';
}
int main(void)
{
    ios::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    int t=1;
    cin>>t;
    while(t--)
    {
        solve();
    }
    return 0;
}

这程序好像有点Bug,我给组数据试试?
