내가 작성한 코드

import java.io.*;

public class qor4592 {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));

        while(true){
            String input = br.readLine();

            if(input.equals("0")){
                break;
            }

            String[] output = input.split(" ");
            int num = Integer.parseInt(output[0]);

            for(int i = 1; i<num; i++){
                if(output[i].equals(output[i+1])){
                    continue;
                }
                else{
                    bw.write(output[i]+" ");
                }
            }
            bw.write(output[num]+" $");
            bw.newLine();
        }

        bw.close();
    }
}
