Problem 1516. Put m balls into n boxes

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
