Wunderkuutio

A competition entry for http://www.wunderdog.fi/wunderkuutio/

Used technologies, tools and practices

• JavasScript, ES6, Babel, Node.js, Mocha, JSHint
• Ruby (1.8.7 because it's pre-installed in the hashicorp/precise64 box I used)
• Ansible, shell scripting, Vagrant, Virtualbox
• TDD

Results

Found a total of 1176 words (see RESULTS.md) in 7157 ms.

Implementation explained shortly

1. on npm test a ruby script reads the two raw txt files and generates two json files; one for words and one for the cube

• words that contain characters which are not present in the cube are filtered out (less work for JavaScript)

2. the cube letters are mapped to x, y and z coordinate space
3. letter chains are processed recursively

• invalid chains (e.g. 'aak') are cached and the next processed words with these letter chains are ignored immediately

Aimed for readable, testable and modular code. More detailed info in finder.js and tests.
