IZHO18 nice sequence

Revision en2, by enoone, 2018-12-21 20:17:22

I am now trying to solve problems from IZHO 2018. I have already done 3 problems, but now I am stuck on problem 2 from the second day called "nice sequence". I don't have any idea and can't find the solution anywhere. Can you help me?

P.S. You can find the problem here.
