How to participate in Google Hash Code Programming competition 2019

Are you looking for a challenging Programming competition which also gets you recognition as well? Google is organizing its annual Hash Code competition for programmers and working professionals for the coming year of 2019. Google Hash Code allows the worldwide programmers to compete and win a chance to visit Google's Dublin Headquarters. This article gives complete information and details regarding Google Hash Code.


Google Hash Code is a programming competition among teams (with the team), which is organized by Google, for the current students and working professionals around the globe. You can pick your team members and your choice of comfortable programming language and later on Google will pick an engineering/technical problem for your team to solve. Coming year's contest starts off with an initial Online based Qualification Round, where you and your team can participate from wherever you feel is comfortable, including from one of their Hash Code areas, also known as Google Hubs. Top performing teams will later be invited to dreamy and lovely Google office for the Final Round formalities.

In order to participate and perform well, one must understand what is the hash code. What do people do with such code? Why is it so important? How does Google manage the passwords of so many users and even makes sure that it is completely secure to have one saved on their browser or in their system? No doubt there are so many algorithms in place, but technology growing every day a common idea becomes a threat to this Search Engine and now advertising giant. This competition is no doubt an effort to make the best use of ever learning and active mind of students and working professionals.

What is Hash Code in Programming?

There are long detailed resources all over the internet which describe in detail, what is the concept of Hash Code. When we enter our password in a system, the actual password is never saved in the client machine database. If this is happening, then this is completely wrong and has flaws.

In order to protect the privacy of the user, and also securing his data, the password is converted into the equivalent Hash code. And this Hash Code is later on saved in the database. Even there are multiple ways to save the Hash Code in the system. Bear in mind that one cannot convert the actual password from the Hash Code, which also makes sure it is safer to be used. As soon as User Logs in, the password is converted and the actual Hash Code is checked against the entered password Hash. If they match, the user is granted access, else error is shown.

Hash Code Competition at Google

The Google's team-based Hash Code competition allows the competitors to share their skills and also get in touch with other programmers when they work together as a team to solve an issue, which is a replica of a real-life challenge! In a small group of two to four, programmers all over the globe will tackle the initial problem via an Online Selection Round. Although this initial round will be running online, participating teams can come together to compete for neck-to-neck level, in locally managed Hash Code hubs, also known as Google Hubs. The top-performing teams from this initial round will be invited to join, international Google office for their annual Hash Code Final Competition.
