            while(cnt > 0){

int main(){

                cout << "0\n";
                continue;
            }
            cout << s[n][(int)s[n].size() - m] << "\n";
            continue;
        }

        n &= 1;
        if((n & 1) == ((s.size() - 1) & 1)){
            n = s.size() - 1;
        }
        else{
            n = s.size() - 2;
        }
        cout << s[n][(int)s[n].size() - m] << "\n";
    }
}

这程序好像有点Bug,我给组数据试试?
