What is the Canadian Computing Competition (CCC)?

The Canadian Computing Competition (CCC) is an annual programming contest organized by the University of Waterloo's Centre for Education in Mathematics and Computing (CEMC). It's open to students across Canada and internationally, featuring Junior and Senior divisions with 5 problems each.

Where can I find CCC solutions?

CCCSolutions.ca provides 270+ detailed solutions to CCC problems from 1996 to 2025, including code in C++, Python, and Java, along with test cases and multiple solution approaches for each problem.

How do I prepare for the CCC?

Practice past CCC problems starting with easier difficulties, study core algorithms (graph theory, dynamic programming, greedy algorithms), and use solution repositories like CCCSolutions to learn different approaches and techniques.

What programming languages can I use for CCC?

The CCC accepts submissions in multiple languages including C++, Python, Java, Pascal, and PHP. Most competitive programmers use C++ or Python. CCCSolutions provides solutions in C++, Python, and Java.
