AIO Algorithms — The Techniques the Contest Rewards
Thirty lessons on the algorithmic techniques that decide AIO scores — sorting, greedy, prefix sums, two pointers, binary search, recursion, dynamic programming and graph basics. Each lesson pairs a clear method with worked examples and hands-on practice drawn from real Australian Informatics Olympiad problems.
AIO pathway: Python Foundation → Algorithms → Olympiad practice.
Need the Python basics first?
If syntax still slows you down, the 20-lesson Python Foundation course gets you fluent in output, input, loops and functions before you tackle algorithms.
