概述

Time Limit: 1sec Memory Limit:256MB

Description

Use pointers on array to write a program that reads in n integers and displays distinct numbers (ie., if a number appears multiple times, it is displayed only once).

Input

The first line is a positive integer t for the number of test cases.
Each test case contains two lines. The first line is an integer n (0<n<=100). The second line contains n integers.

Output

For each test case, outputs the distinct numbers in order in which they were read, seperated by one blank.

Sample Input
