Hashcode is an annual team-based coding competition organized by Google, open to students and professional programmers.

Competitors solve real-life engineering problems by reading data from ranked input files and producing optimal outputs.

Participants are ranked based on accuracy and input file complexity, with larger files offering more points but being more challenging.

GDG Algiers hosts a local hub for the event, providing an additional layer of competition.

Throughout the four-hour coding session, participants receive live updates, snacks, and goodies to stay motivated.

Results are revealed on the Hashcode website, culminating in a gathering for the announcement of the winners.
