Welcome to Google Paris Hash Code!
Google Paris is excited to organize Hash Code, a programming competition where you will tackle a real-life challenge created by Google engineers. Using the programming language(s) and tools of your choice, your task is to develop an original solution to the problem using your coding and algorithmic skills. You will work in teams of two to four members and winning teams will be awarded cool Google prizes.

We hope this will be a lot of fun, and also a great learning opportunity for you to develop your skills, understand the role of an engineer and learn from your fellow peers and Googlers. We look forward to seeing you there!  

Note: Google Paris Hash Code is open only to registered and invited participants. Registration is closed and all invited participants have received a confirmation e-mail. We apologize that we can no longer consider additional applications as the event is fully booked.
