📕 How does it work? 📕

There are two divisions which you have the choice of registering in:

Division 1 1️⃣: Suited to students who’ve competed in competitive programming, have already completed COMP2123 or are stellar at algorithms and data structures.

Division 2 2️⃣: Suited to students just beginning their CS journey, in particular if you have yet to complete COMP2123 or are currently undertaking it this semester. All problems from this division are tailor made to ensure that they are solvable with all the knowledge you’ve learnt so far this semester.

Each division has 4 problems of varying difficulty which you can complete in any order in the 2 hours. The winner is determined firstly by the number of correct problems and then the total time taken to solve the problems in the case of ties (known as the time penalty). The time penalty for a problem is the time taken to solve the problem in minutes + 20min for each wrong submission. So be careful submitting too many wrong submissions!

At the end of the contest, both divisions will have an editorial released afterwards detailing solutions for each problem as well.

‼️While students are free to enroll in whichever division they like, to be eligible for prizes you must match the definitions above. For example, a student who has already completed COMP2123 that enrolls in division 2 is not eligible for prizes for that division (but they are welcome to join for fun). ‼️
