I don't think you have a complete statement of the problem. Why, in the first example, are arrangements like 1 1 2 excluded? And you only accept the arrangements in a particular order. How do you define the order?

Binbin Qi on 11 Dec 2014

the data ascended by column,when the first column is the same, sort by the second column,...

Andrew Newell on 11 Dec 2014

Thanks - and I realize now that 1 1 2 is not excluded; I just wasn't looking carefully.

The best way to generate such a sequence is using depth-first search or recursion. By prohibiting the usage of IFs, all solutions are inefficient (because we can't cut the tree, and are forced to follow all branches).

For the 3 balls 2 boxes cases, shouldn't the following be part of the answer as well?
1 2 1
2 1 1
2 1 2
2 2 1
