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.

Format

MCC will be held on SimpleCMS (our in-house contest system!). Participants will be required to solve 4-6 problems within a two-day window. Participants may work on the problems throughout the two-day window.

Participants may work on the contest anywhere, including at home. Please review the Honour Code section later on this page.

The problem statements will be available in both English and Bahasa Malaysia.

• Each problem consists of a statement describing the problem, and several tasks.
• Each task consists of an input that is unique to each participant.
• For each task, participants will be 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 task has a submission limit independent of each other.
• 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 solve 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 interview.

Sample Problem

Given a list of numbers a_1, a_2, ..., a_n. Output the sum of all numbers.

Categories and Awards

There are three categories for the MCC:

• Bongsu / Junior – Form 1, 2, 3, or Primary school;
• Muda / Intermediate – Form 4, 5;
• Sulung / Senior – Form 6 (lower & upper), Pre-U (Matriculation, Foundation Studies, IB, A-Levels, etc.).

All students will take part in the same competition, but prizes will be awarded by category. There will be Gold, Silver, and Bronze awards.

We will be giving out digital certificates instead of physical ones.

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 2023.
• Invited to the Malaysian Computing Olympiad (MCO), a programming competition tentatively held in April 2024.

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) 2024 which will take place in Egypt.

Organizers

MCC is brought to you by the Malaysian Informatics and Programming Society. See our About page for more details.
