What is MCC?
The MCC (Malaysian Computing Challenge) is an annual online competition designed to evaluate participants’ computational thinking abilities. Knowledge of programming is recommended but not required.
MCC is also the first round in the International Olympiad in Informatics (IOI) Malaysian team selection process.
Format
Contest format
- MCC will be held on SimpleCMS (our in-house contest system!).
- Participants will be required to solve 4-6 problems within a 48-hour window.
- Participants may solve the problems throughout the entire two-day window.
- Only the final score will be used for ranking.
- Incorrect answers and submission time will not affect your ranking.
- Participants may work on the contest anywhere, including at home.
- During the competition, usage of all printed/online resources and tutorials are permitted.
- However, discussing the problems with others is not allowed.
- Please review the Honour Code section later on this page.
Problem format
The problem statements will be available in both English and Bahasa Malaysia.
- Each problem consists of a statement describing the problem and several inputs.
- The inputs are unique to each participant.
- For each input, participants are required to submit an output (by typing/pasting the output into a text box) that satisfies the statement and input.
- Full score for a task will be awarded if the output submitted is correct, zero score will be awarded otherwise. Participants will know whether their submission is correct immediately after it is made.
- Each input has a submission limit independent of each other (to prevent answer spamming).
- Participants will not need to upload code during the contest. As long as they can produce the correct output, they can use any programming language or method (even solving by hand for small inputs).
- The more difficult tasks will likely require programming knowledge.
- Python is recommended for beginners, and C++ is recommended as it is the only language supported in the later rounds (see the Beyond MCC section).
- Participants are encouraged to save any code they have written to be submitted for the exit survey.

Honour Code
All participants in MCC agree that they will:
- Not discuss the problems with anyone else during the competition time;
- Neither share solutions nor post solutions online during the competition time;
- Notify the organizers (
mcc [at] ioimalaysia [dot] org
) immediately if they become aware of other participants cheating.
Beyond MCC
MCC is the preliminary selection process of a year-long program to identify and train the top computing talents in Malaysian schools. Top scorers in MCC will be:
- Invited to a training camp introducing algorithms and algorithmic thinking, tentatively held in December.
- Invited to the Malaysian Computing Olympiad (MCO), a programming competition tentatively held in April next year.
The top scorers in MCO will be called for a series of intensive training camps conducted by experienced Olympiad participants. Students who qualify at this level will participate in the Asia-Pacific Informatics Olympiad (APIO), an annual online contest among countries in the Pacific Rim region. After the training camps and APIO, four students will be selected to represent Malaysia in the International Olympiad in Informatics (IOI).
