/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
    public static void main (String[] args) throws java.lang.Exception
    {
        // your code goes here
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        int[][] data = new int[n][];
        int[] result = new int[n];
        for (int i = 0; i < n; i++)
        {
            int m = in.nextInt();
            data[i] = new int[m];
            int o = 0;
            for (int j = 0; j < m; j++)
            {
                int l = in.nextInt();
                Boolean b = false;
                for (int k : data[i])
                    if (k == l) b = true;
                if (!b) data[i][o++] = l;
            }
            Arrays.sort(data[i]);
