Can you find all the cases where, if I put 3 balls into 2 boxes

the case is

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

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

So we have 4 cases

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

Example

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

1 1 1 1 1 2 1 1 3 1 1 4 1 2 2 1 2 3 1 2 4 1 3 3 1 3 4 1 4 4 2 2 2 2 2 3 2 2 4 2 3 3 2 3 4 2 4 4 3 3 3 3 3 4 3 4 4 4 4 4
