What is Project Euler?

quoting from project euler home page

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.

What about the solutions?

I will try to solve the problems using mainly Ruby and Java. Eventually, I can pick another language, just for fun. Each problem will have its own readme file, with instructions about how to execute the solution.

Running

You will need:

• Ruby 1.8.x or 1.9.x - you can install using RVM
• Bundler - http://gembundler.com/

All solutions together

Just type the following commands in the project root directory:

>> bundle install
>> rake

All the specs, for all the problems, will run.

An especific problem

>> cd problemX
>> bundle install
>> rake

TADA! That is it.
