#include <iostream>#include <string>#include <cctype>#include <vector>#include <algorithm>

using namespace std;int main(){     string word;     vector<string> vec1;    // empty vector

     while (cin >> word)  {         vec1.push_back(word);     // append word to text

/*一种*/    copy(vec1.begin(),vec1.end(),ostream_iterator<string>(cout," "));   cout<<endl;

/*二种*/

     vector<string>::iterator it;    for (it=vec1.begin();it!=vec1.end();it++)       cout<<*it<<" ";      }

  return 0;}
