The Catalyst Coding contest (CCC) will take place this year on Friday the 27th of April 2018, at the University of Salzburg's Department of Computer Science in the Techni-Z. The CCC is an international programming competition, held in 22 countries.
The participants are given a programming task, which are tiered by difficulty. They then have 4 hours and whoever finishes the most levels by the end, wins the competition. Aside from that, each participant will get the ability to measure themselves against all the other programming participants.
