Geek hosted a coding competition, some of the questions were easy and some of them were hard. You are given an array arr of positive integers of size N and an integer K, arr[i] represents the hardness of each problem of geeks' contest. Among those N numbers, your task is to find the numbers which appear more than K times and print them in increasing order. If no number appears more than K times than print -1.
Input:
1. The first line of the input contains a single integer T 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 contains N space-separated positive integers represents array arr.
Output: For each test case, print the maximum number of chocolates you can collect
Constraints:
1. 1 <= T <= 10
2. 1 <= K, N <= 100000
3. 1 <= arr[i] <= 10^9
Example:
Input:
3
3 1
5 5 6
6 1
2 2 3 3 4 4
4 2
1 2 2 3
Output:
5
2 3 4
-1
Explanation:
Test case 1: The only problem with hardness 5 appears more than once
