description: It is the hard version of the problem. The only difference is that in this version 1 ≤ n ≤ 300.
  
  In the cinema seats can be represented as the table with n rows and m columns. The rows are numbered with integers from 1 to n. The seats in each row are numbered with consecutive integers from left to right: in the k-th row from m (k - 1) + 1 to m k for all rows 1 ≤ k ≤ n.
  
  1| 2| ⋅⋅⋅| m - 1| m  
  ---|---|---|---|---  
  m + 1| m + 2| ⋅⋅⋅| 2 m - 1| 2 m  
  2m + 1| 2m + 2| ⋅⋅⋅| 3 m - 1| 3 m  
  \vdots| \vdots| \ddots| \vdots| \vdots  
  m (n - 1) + 1| m (n - 1) + 2| ⋅⋅⋅| n m - 1| n m  
  The table with seats indices
  
  There are nm people who want to go to the cinema to watch a new film. They are numbered with integers from 1 to nm. You should give exactly one seat to each person.
  
  It is known, that in this cinema as lower seat index you have as better you can see everything happening on the screen. i-th person has the level of sight a_i. Let's define s_i as the seat index, that will be given to i-th person. You want to give better places for people with lower sight levels, so for any two people i, j such that a_i < a_j it should be satisfied that s_i < s_j.
  
  After you will give seats to all people they will start coming to their seats. In the order from 1 to nm, each person will enter the hall and sit in their seat. To get to their place, the person will go to their seat's row and start moving from the first seat in this row to theirs from left to right. While moving some places will be free, some will be occupied with people already seated. The inconvenience of the person is equal to the number of occupied seats he or she will go through.
  
  Let's consider an example: m = 5, the person has the seat 4 in the first row, the seats 1, 3, 5 in the first row are already occupied, the seats 2 and 4 are free. The inconvenience of this person will be 2, because he will go through occupied seats 1 and 3.
  
  Find the minimal total inconvenience (the sum of inconveniences of all people), that is possible to have by giving places for all people (all conditions should be satisfied).
  
  Input
  
  The input consists of multiple test cases. The first line contains a single integer t (1 ≤ t ≤ 100) — the number of test cases. Description of the test cases follows.
  
  The first line of each test case contains two integers n and m (1 ≤ n, m ≤ 300) — the number of rows and places in each row respectively.
  
  The second line of each test case contains n ⋅ m integers a_1, a_2, …, a_{n ⋅ m} (1 ≤ a_i ≤ 10^9), where a_i is the sight level of i-th person.
  
  It's guaranteed that the sum of n ⋅ m over all test cases does not exceed 10^5.
  
  Output
  
  For each test case print a single integer — the minimal total inconvenience that can be achieved.

  Note
  
  In the first test case, there is a single way to give seats: the first person sits in the first place and the second person — in the second. The total inconvenience is 1.
  
  In the second test case the optimal seating looks like this: 
  
  <image>
  
  In the third test case the optimal seating looks like this: 
  
  <image>
  
  The number in a cell is the person's index that sits on this place.
