Given an array arr of integers of size N and an integer K, the task is to find the K distinct larger values of the array. If there are less than K distinct values in the array print -1.
1. The first line of the input contains a single integerT denoting the number of test cases. The description of T test cases follows.
2. The first line of each test case contains two space-separated integers N and K
3. The second line containsN space-separated positive integers represents array arr.
Output: For each test case, print K space-separated values in decreasing order
1. 1 <= T <= 10 2. 1 <= K <= N <= 100000
3. 1 <= arr[i] <= 10^9
