import java.util.Scanner;

public class CheckDuplicates {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String[] str = in.nextLine().split("\\s");

        for (int i = 0; i < str.length; i++) {
            boolean found = false;
            for (int j = 0; j < i; j++) {
                if (str[i].equals(str[j])) {
                    found = true;
                }
            }
            if (!found) {
                System.out.print(str[i] + " ");
            }
        }
        System.out.println();
    }
