According to Cody Problem 1516, if I put 3 balls into 2 boxes then

     1     1     1
     1     1     2
     1     2     2
     2     2     2

The columns stand for a ball, the number stands for a box, and the row stands for a case.

Now we count the number of balls in each boxes.

so we get

     3     0
     2     1
     1     2
     0     3

the 1-th row stand for the 1-th case,3 balls are put into the first boxes,the others is empty the 2-th row stand for the 2-th case,2 balls are put into the first boxes,1 balls is put into the second boxes

You should write a function, input m and n, m stand for the number of balls ,n stand for the number of boxes,output all the cases.

Example

If m = 3,n = 4, you should output

     3     0     0     0
     2     1     0     0
     2     0     1     0
     2     0     0     1
     1     2     0     0
     1     1     1     0
     1     1     0     1
     1     0     2     0
     1     0     1     1
     1     0     0     2
     0     3     0     0
     0     2     1     0
     0     2     0     1
     0     1     2     0
     0     1     1     1
     0     1     0     2
     0     0     3     0
     0     0     2     1
     0     0     1     2
     0     0     0     3
