CCC Junior Qualification Round


A malicious Distributed Denial of Service (DDoS) attack targeted the Beaver Computing Competition (BCC) on the morning of the competition. However, we have not revealed this attack until now. Despite the best efforts to get an alternate server up and running in time, students’ answers were all deleted when they submitted. This disruption affected schools and students in many different ways. These varying circumstances mean it is not reasonable for students to determine for themselves if they are ready for the junior division of the Canadian Computing Competition (CCC Junior). So in order to provide a fair opportunity for all eligible students, we will be holding an additional competition. This Canadian Computing Competition Junior Qualifying Round (CCCJQR) will be the primary basis on which students can determine if they are ready for the CCC Junior.

Date and Time

The CCCJQR will be held on Friday, April 1, 2016. The contest must be written between 7:00am and 12:00am the following day, Eastern Daylight Time. The contest was originally going to be only 2 hours in length, but we would like to give all programmers a chance to complete all problems.


Any student will be allowed to participate but the contest is primarily intended for students with very basic programming skills hoping to write the CCC Junior. In order to limit these additional demands on supervising teachers, we are recommending that each school only select a small number of students to participate. However, any student who wishes to write the CCCJQR may do so.


The CCCJQR administration, registration and competition procedures will run as original planned for the BCC. However, there will be no cost for students to participate.

Format and Structure

The CCCJQR will be a two-hour contest composed of 5 problems roughly easier than the difficulty level of the first problem of a CCC Junior Contest. Participants must use the Don Mills Online Judge, since we were unable to acquire another server specially dedicated to the CCCJQR. Otherwise, the same languages, rules and format will be the same as for the CCC.


The DMOJ will be available for practice. It is highly recommended that participants can solve problems that are worth at least 1 point.

Other Information

  • The CCCJQR will replace the BCC in its role in determining if a student is ready to write the CCC Junior contest.
  • As always, a student’s readiness to write the CCC Junior contest remains at the discretion of the student.
  • There are no prizes for CCCJQR, except for pointless bragging rights.
  • We will not be publishing summary results of the CCCJQR, since it is not economically feasible.
  • Also, we are not affiliated with any university.

    Some of you guys seem to be stuck on P3, so I'll give you a hint.

    There is a very, very quiet audio clip that plays on P2. You need to turn your volume to max and you might need headphones or earphones to hear the clip properly. The audio clip will give you an idea on how to do P3.
