On the Livebook dependencies,
Mix.install([
{:smaoc, git: "https://github.com/nettinho/smaoc"}
], force: true)
Just select the SmartCell, choose the date and fetch the puzzle.
You can fill in the example textarea copying and pasting from the problem description.
Implement the &Smaoc.Solution.solve/2

If you return the answer, your may submit it directly from the livebook.
