Yeah, like others, my āsolutionā isnāt worth posting here because it only checks to see if the number of tiles can fit in provided area. It doesnāt look at shapes, flips, or rotations. Good enough, Iām done.
I just wanted to thank @lud , @bjorng , @hauleth and others here for providing your code for me to look at. All of you have such great and elegant understanding of functional programming and Elixir, I feel like I learn a lot reading your code. Now if I could only apply what I learn in my own code 
. Anyway thanks.
Someday, after the holidays, Iām going to go back to Day 10 Part 2. Thatās the only one I could not crack on my own, having to resort to a third-party solver. I have some more ideas that I want to try.
Happy Holidays!
