Hash Code is a team programming competition organized by
Google. You pick your team and programming language, we pick a
Google engineering problem for you to solve. Are you up for the
For each round of the competition we’ll present a problem
(see past problems here)
and your team will write a program that generates a solution.
Your team can submit as many solutions as you'd like using the online
Judge System, and a live scoreboard will let you know how you stack
up against the competition. Top scoring teams will win cool Google
prizes, because of course you can’t host a programming competition
without something to work for! Convinced?
Sign up today for Hash Code 2018.
Hash Code is open to university students and industry professionals
in Europe, the Middle East and Africa. Participants
compete in teams of two to four. Registration is free of charge and
will close on 26th February 2018 at 18:00 CET.
Your team will be tasked with solving a challenge
created by Google engineers using your own computer and
programming language and tools of your choice. For this round,
your team can compete from wherever you’d like,
including from one of our Hash Code hubs.
We’ll release the problem statement as a PDF file that can
be downloaded from the Judge System. You’ll be able to
submit your team’s solution through the Judge System at any
time, and a live scoreboard will be available.
A few minutes after the
submission deadline, we’ll join you again via YouTube Livestream to
announce highlights and the first place team from the Online
Qualification Round. Soon after, we’ll release the final scoreboard on
the Judge System so that your team can compare its achievements with
others. The final results will be announced by 6th March 2018 and all
teams who have qualified for the Final Round will be notified then.
What do I need to participate?
The only thing you need for the Online Qualification Round
is a computer connected to the Internet. We will announce
the problem through a YouTube Live Stream, please check
that your computer is able to play YouTube videos
beforehand. The Judge System will be available as a web
application, compatible with recent web browsers. For the
rest of your computer setup, you're free to use the tools
and programming languages of your choice.
How will I receive
We will add all participants to a mailing list, and will
send all relevant information there (so monitor your
mailbox!). The problem statement will be available on the
Judge System, and we will also post any clarification to
the problem statement there. You’ll also be able to get in touch
with us over email if you have any questions.
How should I prepare?
You should carefully review the rules
of the competition. It may also be helpful to look at
problem statements from
past editions of Hash Code. We encourage you to
practice together with your teammates, and agree on the
programming languages and tools you'd like to use. You should
prepare an empty "Hello World!" project on your
computer, with a script to generate the ZIP file to
upload the source code to the Judge System.
Dublin office is located on Barrow Street in Dublin,
Ireland. Set in booming Silicon Docks (the Irish equivalent of
Silicon Valley), our Dublin campus is home to a diverse community of
Googlers who hail from over 60 different nationalities.
What about travel and
Participants will be responsible for arranging their own travel
and accommodation. Participants will be able to apply for a travel
grant from Google (between 100 and 500 EUR) in order to help offset
these costs. If selected, participants will receive the grant after
the Final Round takes place.
What do I need to bring?
The only thing you absolutely need to bring is your own
laptop (with its charger!). You may also bring your own
separate keyboard and mouse, but this is not a must. We
