Project Euler in Groovy
Project Euler is a great way to focus your skills on programming languages and techniques. From the website:
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.
I used Groovy 2.0.5 to explore type safety in Groovy to solve practical programming problems. For now, I will post a link to my Groovy Project Euler GitHub project, with analysis to come in the future. Currently, I have completed the first ten programming problems.
