Our journey
The beginning
Chris Robart at Milliken Mills HS started publishing CCC solutions in Turing and Java for his students.
Transition to Python
Solutions were ported to Python as it became the dominant teaching language for high-school CS.
Modernization
The repository was rebuilt as an open-source site with multi-language solutions, full test data, and a community-editable archive.
Refresh
A visual rebuild of the site, along with a new forum and backend. Coming soon :)
A special thanks
The original solutions came from two Milliken Mills H.S. teachers who have been key in creating and maintaining this website. Enjoy your retirement!
