The 2013 Progsoc Code-a-thon will be a friendly and fun competition held for everyone. Individuals and teams will work to solve programming problems ranging from easy problems to more difficult problems.

Prizes will be awarded for every question solved!

The competition will be held in an open space and competitors must bring their own laptops. Marking of answers will be done manually by a Progsoc judge.


The competition will be held on:

Tuesday 28 May 2013 from 16:00 until 19:00 EST

The location is:

City Building 1, Level 3A, Concourse Area

Competition programming languages:

Any language of your choice.

Marking of answers:

Both the algorithm and the output of your code will be assessed for correctness. It will be manually marked.


Individuals and teams (of 2 or 3 people) will be able to register their teams online. Please register your details here.

Who Can Enter

  • Current UTS students
    • Both undergraduate and postgraduate students are eligible
    • Students from ALL faculties are welcome

What to bring

  • Your laptop
  • Pen and paper


Prizes will be awarded for each problem solved. Both individuals and teams will receive 1 prize per question solved. Different prizes will be awarded based on the difficulty of the problem.

  • Beginner problem: Your choice of lollies!
  • Advanced problem: 1 movie voucher


  1. Entrants will have a total of 3 hours to solve as many problems as they want.
  2. Entrants are free to enter the competition at any time, and free to leave at any time. However, competitors cannot enter the competition then return later. This is to prevent cheating.
  3. Solutions must not be obfuscated, and should clearly show the algorithm used to solve the problem.
  4. The judges' decision is final.

Example Problems

To cater for a variety of ability levels, there will be 2 different difficulty levels:

Beginner Problems

These will be set at the level of Project Euler problems.

Example: Write a program that adds all the natural numbers (i.e. positive integers) below one thousand that are multiples of 3 or 5.

Possible solutions

Advanced Problems

These will be set at a level a bit easier than the level of ACM ICPC Regional Competition Problems. A few examples:
