#include<string>
#include<vector>
#include<algorithm>
#include<fstream>

using namespace std;

int main(int argc, char **argv) {
    ifstream ifile(argv[1]);
    ofstream ofile(argv[2]);
    string line;
    vector<string> data;
    while (getline(ifile, line)) {
        data.push_back(line);
    }
    sort(data.begin(), data.end());
    for (const auto &i : data) {
        ofile << i << std::endl;
    }
    return 0;
}
