I was thinking about it and wanted to add that but script has no
concept about other nodes and I assumed people will use use it only
for "hard ones". Tough if you think printing sample output only for
those two/three nodes I will add it.

Also thought about that but numbers are quickly becoming big so wanted
to stop the search asap. I remember you saying that there are some
issues with "big node numbers" so that's why I decided to print first
one. Is there any upper limit that I could use?

Ok, Will do that

OK, will clean up it was supposed to be just a poc to "start discussion"

I think current (naive) approach could scaled up to 3, maybe 4. For
more I think there might needed some more "mathematic approach" to
this issue. I think there should be some algorithm that does what we
want just I don't know it :)
