The first six days of this years Advent of Code challenge are now written up at Study Q. Ive trawled q solutions from multiple sources to extract maximum joy, and explored and discussed variations. The solution pages are written to help the rest of us learn from the star qbists, and they come with scripts and input files. Lots here to chew on and deepen your use of iterators, projection and composition
Day 5 includes code to animate the solution in your console (thank you, Cillian!) and a GIF of the animation.
There is also a one-page listing of solutions in exhibition form: terse and without explanation. It will scare and impress most of your friends and inspire a few to learn q.
Enjoy!
