Here you will find a bunch of essential Algorithms that you must understand for your exams.

Each document highlights the basic theory aspect of each algorithm, an example of the code used within Python, the different variants of the algorithm and downloadable python/text files to see the code in action.

**Note: You do not need to write in purely pseudocode in your exam. It is perfectly appropriate to answer questions using the program language you have learnt. I will be demonstrating the following algorithms in Python.**
