Program compiles fine on my machine but failed to compile by LeetCode

    using namespace std;

      stack<string> elems;
      stringstream s(str_to_split);

      void reverseWords(string &s) {
        if (s.empty()) {
        stack<string> st = split(s, ' ');
        vector<string> st_contents;
        while (!st.empty()) {
          if (
          st_contents.push_back( );
        ostringstream os;
        copy (st_contents.begin(), st_contents.end(), std::ostream_iterator<string>(os, " "));
        // remove the trailing space
        s.erase(std::find_if(s.rbegin(), s.rend(), std::not1(std::ptr_fun<int, int>(std::isspace))).base(), s.end());
        s = os.str();

    I got compiler error: 'ostream_iterator' was not declared in this scope, but it works on my local machine (gcc 4.7 Ubuntu 64). Anyone knows why?

    You do not need to do #include <...> as it would be automatically included for you. In fact, all your #includes will be stripped away. In this case, ostream and iterator is not supported, and hence the compile error. I don't think you need fancy library in order to solve this problem.
