The first line of the input contains an integer, 'T’ denoting the number of test cases.
The first line of each test case contains two space-separated integers, 'N' and 'K', denoting the number of elements in the array 'ARR', and the special number respectively.
The second line of each test case contains 'N' space-separated integers denoting the elements of the array 'ARR'.
For each test case, print the minimum number of transactions needed to make the wallet balance of all the friends equal.
Print the output of each test case in a new line.
You do not need to print anything. It has already been taken care of. Just implement the given function.
1 <= T <= 10
1 <= N <= 10^5
1 <= K <= 10^4
0 <= ARR[i] <= 10^4
Where 'ARR[i]' represents the ith element of 'ARR'.
