Helvetic Coding Contest 2025
Event start time 12.4.2025 10:30

The Helvetic Coding Contest, known as HC², is the biggest programming contest in Switzerland. Held over one day on the EPFL campus, it gathers over 200 participants ready to code. After four years, the Polympiads association successfully brought back the event last year and will do so again this year! There will be cool prizes for both top-performing teams and randomly selected teams. No prior competitive programming experience is needed. From last year we know that teams with no previous competitive programming experience also had lots of fun!
This event is open to every ETH member, including non D-INFK students and PhDs.
