Weekly Coding Challenge

Coding Challenge is a community service that publishes one coding challenge per week. Sources will range from textbooks to interview questions to community-submitted content. Topics will range between general coding practices to engineering problems.

A problem will be posted each week with all reasonably valid solutions posted one week later. Comments aren't discouraged but a good solution will be self-explanatory and easy to read. Only solutions posted from http://gist.github.com/ or a public GitHub repo will be accepted.

Check the PivotalTracker Project Page if you would like to contribute. Contributing is easy:

1. For the project
2. Create a topic branch
3. Create tests and ensure you didn't break anything.
4. Submit pull request.

Setting up Weekly Coding Challenge locally

The only dependency is postgresql, which can be installed pretty easily by a reasonably competent programmer. This [very short] guide assumes you don't have Ruby installed.

1. Install postgresql
2. Install Ruby
3. Start postgresql
4. Clone the project
5. run bundle install && bundle exec rake db:create
6. run bundle exec rails server
7. The application should be running at http://localhost:3000
8. ???
9. Profit!
