Math python question

[deanhystad]

What do you mean by "cannot be put together" and "works"? Does [(1, 2), (25, 99), (8000, 9999)] work? Are you looking for no duplicates, or do the numbers also have to be sequential like [(1, 2), (3, 4), (5, 6)]? If sequential, do the numbers have to be in the sequential order, or is [(1, 5), (4, 2), (3, 6)] work?

More details please.
