You are given an array A of size N. The array contains almost distinct elements with some duplicated. You have to print the elements in sorted order which appears more than once.

Input Format:
The first line of input contains T, denoting the number of testcases. T testcases follow. Each testcase contains two lines of input.  The first line of input contains size of array N. The second line contains N integers separated by spaces.

Output Format:
For each test case, in a new line, print the required answer. If there are no duplicates print -1.

Your Task:
Your task is to complete the function SortedDuplicates(arr, n) which accepts array and its size as an argument.

1 <= T <= 100
1 <= N <= 100
1 <= Ai <= 106
