10105 – Polynomial Coefficients
I must be stupid, but I had a hard time understanding what this problem was asking. After I figured that out, it wasnâ€™t so bad, and the solution was pretty straightforward.
10077 – The Stern-Brocot Number System
I enjoyed this problem. It wasnâ€™t particularly difficult, but at least I got to play with something novel in the process. My solution is available, as always.
One more problem to go, and then Iâ€™m on to the combinatorics chapter!
