Problem 624

Post by hexadoodle »

Gosh! It's never a good sign when I've been at a brick wall with this problem and there's no problem thread. :)
I wanna say I'm almost there, got closed forms for everything, not brute forcing anything, but I must be missing something really simple given how many people have solved this.

EDIT: Got it. I had most of the right ideas but I had to dig to find the error in my code.

A little late, but good for you! Hopefully, I should also be able to solve this problem.

EDIT: I can match the example for P(2), but my modular arithmetic skills are not enough to get me across the line on this one!
