[Pointers and C-String]D. Liang 7.2 Printing distinct numbers

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, separated by one blank.

Sample Input:

Sample Output:

Programme:
