Number Theory Problem from UVA (UVA 11774 — Doom’s Day)

Revision en1, by Tobby_And_Friends, 2017-01-11 15:47:41


I understand that the for n == m answer is 2. But I can't figure out the solution when n != m. I mean I basically do not understand the theory behind the solution (apart from trying out for small test cases). Any help is really appreciated.
