The CCC is an individual, online competition, which means that students must complete the exam at school under supervision.

Who Can Participate in the CCC?

One of the most exciting aspects of the CCC is that it is open to all students, regardless of grade level or prior experience. Unlike some competitions that impose strict eligibility criteria, the CCC allows participants to select their competition level based on their coding proficiency rather than their grade level.

Choosing the Right Level:

✅ Junior Level – Ideal for students with beginner programming skills. If you’re familiar with basic loops, conditionals, and simple algorithms, this level provides an opportunity to practice fundamental problem-solving techniques in a competitive setting.

✅ Senior Level – Designed for students with intermediate to advanced programming experience. If you’re comfortable with sorting algorithms, recursion, and mathematical problem-solving, the Senior level offers a challenging set of algorithmic problems that test efficiency, logic, and optimization skills.

Students can choose the best level for themselves, meaning that even younger students with strong programming backgrounds can compete at the Senior level if they feel prepared.

Contest Format & Scoring

The CCC is a three-hour-long programming contest with five questions per competition level. The questions increase in difficulty, and each is worth 15 points, for a total score of 75.

Junior Level Breakdown:

• Questions 1 & 2: Basic programming concepts (loops, conditionals).
• Questions 3 & 4: More complex logic, often requiring nested loops and structured problem-solving.
• Question 5: A challenging problem that may involve recursion, multi-dimensional arrays, or efficient algorithm design.

Senior Level Breakdown:

• Questions 1 & 2: Basic sorting and searching algorithms.
• Questions 3 & 4: Advanced counting techniques, recursion, and mathematical problem-solving.
• Question 5: A high-level, IOI (International Olympiad in Informatics)-style problem requiring optimization and algorithmic efficiency.

Partial Scoring & Subtasks

The CCC allows students to earn partial credit by solving simpler versions of a problem. Each problem may be divided into subtasks, where solving the easier version earns partial points, and the more difficult version earns full credit. This system makes problems more approachable for students at different skill levels.

Programming Languages Allowed

Students can write their solutions in C, C++, Python 2, Python 3, or Java. However, language choice can affect scoring, as Python and Java tend to be slower for complex problems. C++ is the preferred language for top competitors, as it offers faster execution times and better memory management.

How to Prepare for the CCC?

1. Solve Past CCC Contests

One of the most effective ways to prepare for the Canadian Computing Competition (CCC) is by practicing past contest problems. This not only helps students familiarize themselves with the competition format but also allows them to recognize common problem-solving patterns that frequently appear in the contest. By working through previous questions, students can refine their coding techniques, improve efficiency, and develop a structured approach to tackling algorithmic challenges. Regular practice with past problems builds confidence, speed, and adaptability, all of which are crucial for excelling in the CCC.

3. Learn Competitive Programming Techniques

For Senior-level participants in the Canadian Computing Competition (CCC), mastering efficient algorithms is essential for tackling the more advanced problems in the contest. Since the difficulty level increases significantly, students must develop a strong foundation in algorithmic thinking, optimization techniques, and problem-solving strategies. To build these skills, two highly recommended books provide in-depth guidance on competitive programming techniques.

• Competitive Programming by Halim & Halim offers comprehensive explanations of algorithms, data structures, and problem-solving strategies, making it an excellent resource for students aiming to perform well in contests like the CCC and the International Olympiad in Informatics (IOI).
• Competitive Programmer’s Handbook by Antti Laaksonen is another recommend read, covering sorting, searching, graph theory, dynamic programming, and more, with clear examples and practice problems that help students develop efficient solutions for time-constrained problems.

By studying these resources, students can enhance their algorithmic efficiency, improve their problem-solving speed, and gain a competitive edge in the Senior division of the CCC.

4. CEMC’s in-school workshops

Students can take advantage of CEMC’s in-school workshops, where experts visit schools to conduct problem-solving sessions and teach advanced computational techniques.
