v

An integer number is interesting if it appears at least k times in a list. Given N integer numbers, and another integer k, your task is to find how many interesting numbers are there in the list. Input The input will start with an integer T (100 > T > 0), denoting the number of test cases to follow. Each test case starts with a line containing two integer numbers N (0 < N < 100) and k (0 < k < N). Then the next line contains N integer (32-bit signed) numbers separated by spaces.

Output For each test case, there should be one line of output, containing the count of interesting numbers.

Sample

Input	Output
2 7 2 10 3 20 20 3 8 3 5 4 10 3 3 2 98	2 0

Explanation of the inputs and outputs:

The first number (2) denotes the total test cases.

The first test case has N = 7 and k = 2

There are 7 numbers in the list (10, 3 ) of which 10 appears once, 3 appears 3 times, 20 appears twice, and 8 appears once. Since k = 2, then 10 and 8 are not interesting (they appear less than 2 times). Therefore, 3 and 20 are interesting, meaning, there are 2 interesting numbers. So, the output is 2.

In the second test case, k = 4, and since there is no number appearing at least 4 times, there is no interesting number. Therefore, the output is 0.
