Week 5 Summary

Posted by Ethan Brown 💜 Friday 06 February 2026, 02:18:25 PM.

Hi everyone!

It's the last week of the course! Almost there. Putting this out a little early to make sure you get an update prior to the myExperience closing date.

Standard stuff:

• We covered the last couple of topics this week: heaps and tries, as well as running a revision session.
• In tutorials, we went over hashing, heaps, and tries. Solutions for all tutorials are now available.
• Lab marking for lab04 will be completed this coming Saturday for those without extensions, so take a look at that before the exam.
• Quiz 4 was due on Wednesday, but if you still haven't submitted, you have until Monday to do so (with late penalty).
• Assignments are now hopefully all submitted, but late submissions are allowed until Saturday 8pm, with the appropriate late penalty.

And finally, the exam is on Monday, the 9th of February. You should have received details for this already, but you can find your seating allocation on the WebCMS sidebar as well. Check the Exam Information page and get yourself ready.

Please fill in myExperience . This is the best way to let us know what needs to be improved,or what was good and should continue. Please be constructive in your feedback; I can't do anything with "the course sucked," but I can with "this particular part of the course should have included this." The survey is due tonight at midnight!

There is also an incentive for completing this, of a hint in the exam for a random programming question for 60% participation and every additional 10% beyond that. At the moment, the participation rate is only at 42% , so please fill it in if you haven't.

Good luck everyone!

Week 4 Summary

Posted by Ethan Brown 💜 Sunday 01 February 2026, 01:18:15 PM.

Hi everyone!

Today marks the end of week four, so here's a summary of the week and things to look out for:

• We only had one lecture day this week, covering the hash tables topic. We'll be covering heaps and tries this coming Monday, then on to revision.
• A reminder to fill in the revision topic form if you haven't already (found here ). This will inform what we go through on Tuesday during the revision lecture. Please be specific; I will not be covering entire topics or algorithms, as you can just check the slides for those, please tell me exactly what has you stuck.
• In tutorials, we went over traversal and various algorithms on graphs.
• In labs, we went over minimum spanning tree implementations. This will be the last lab for the term! Lab 3 automarking is also available for those without extensions. Those with extensions will be available next weekend.
• Quiz 3 is still technically able to be submitted, if you haven't already. Your last quiz of the term is also available, quiz 4, covering hash tables, heaps, and tries, due this coming Wednesday. You can take a look at last term's slides if you want to finish it early, but you'll have everything you need to finish it by tomorrow afternoon.
• Tutorial 5 is available now! Your last tutorial for the term
• Please fill in myExperience . This is the best way to let us know what needs to be improved,or what was good and should continue. Please be constructive in your feedback; I can't do anything with "the course sucked," but I can with "this particular part of the course should have included this." The survey is due Friday midnight.
  • There is also an incentive for completing this, of a hint in the exam for a random programming question for 60% participation and every additional 10% beyond that.
• Don't forget to submit your assignment! This is due tomorrow 8pm, so make sure you're on top of it, else you'll be eating into your final exam revision time.

Good luck everyone!
