478B

Hello! I am completing 100 DivB problem in Ahmed's Ladder and I got stuck on this one. I feel this one has some underlying mathematics concept I am unaware of. Sadly there is no editorial either and understanding from other people's code was very difficult.

Can someone give me a hand in understanding the solution to this problem?

Thank you very much
