#include <iostream>
#include <sstream>
#include <string>
#include <vector>
#include <iterator>

int main()
{
    std::string line;
    while (std::getline(std::cin, line))
    {
        std::vector<std::string> strs;
        std::istringstream ss(line);
        std::copy(std::istream_iterator<std::string>(ss), std::istream_iterator<std::string>(), std::back_inserter(strs));
        std::copy(strs.begin(), strs.end(), std::ostream_iterator<std::string>(std::cout, "\n"));
    }
    return 0;
