Wow, this is so cool! My goal of this year is much more simpler. Hopefully this year, I will solve all of them using a Functional programming Language named Elixir [0].
So far, I'm loving it! The source code is available on GitHub [1]
The repository also contains couple of mix tasks to generate boilerplate codes for each solve. And update the readme automatically on each commit to list the problems that I've solved so far.
