void split(const string &str, vector<string> &res, const char pattern) {     istringstream is(str);     string temp;     while (getline(is, temp, pattern))     {         if (temp.length() != 0)         {             res.push_back(temp);         }     }               return; }     void trim(std::string &s) <br>{     if (s.empty())         return;     s.erase(0, s.find_first_not_of(" "));     s.erase(s.find_last_not_of(" ") + 1); }
