Fun Facts About CCC (Canadian Computing Competition)

• Before 2013, CCC was judged by school teachers by running students' code on the teacher's laptop, typing input by hand, and comparing output manually. This is why all question inputs are relatively small.
• Before using the CCC grader, teachers needed to burn top students' code onto a CD and then mail the CD to Waterloo for double-checking.
• In 2016, a malicious Distributed Denial of Service (DDoS) attack targeted the CCC Online Grader on the contest day. It took almost the entire day to fix. This is why the extra round, CCOQR, was introduced.
• Who created the most CCC questions? Likely SourSpinach.
• What's the lowest CCO cutoff line? 45 out of 75 @ CCC 2010 (based on memory).
• What's the highest CCO cutoff line? 72 out of 75 @ CCC 2013.
• What topics are tested the most in past CCC? Graph Theory in Senior and Implementation in Junior.
