Hello Anon! First of all, thanks for solving the problem, I appreciate it. Unfortunately I believe your answer is wrong. I have attached an image for some small cases. I hope I wrote them correctly, you could write them out yourself to check since for small n it is not that hard I believe.

Greetings anon! You seem to have found the clever solution(the book has 2(well actually 3) solutions). However unfortunately your final answer seems to be wrong. But your general idea seems to be identical to the second solution in the book. I'll post as a separate reply the image of the second solution taken from the book I got this problem from(it uses different words but it's the same problem). Please let me know if this all clears it up or if I'm perhaps misunderstanding something. Also Merry Christmas once again!
