Essential algorithms for A level Computer Science (First edition)

The aim of this book is to provide students and teachers of AS & A level Computer Science with a comprehensive guide to the algorithms students need to understand for examinations.  Each chapter presents:

  • a data structure or algorithm, explaining how it works
  • real-world applications of the algorithm
  • a step-by-step example
  • pseudocode
  • actual code in two languages (Python and Visual Basic)
  • a description of the space and time complexity.

We have chosen to provide coded solutions in Python 3 because it is the most popular language taught at GCSE, and in Visual Basic Console (2015 onwards) because it is a language that most closely resembles the pseudocode and coded examples students will need to work with in examinations.

This book is also available as a printed copy from amazon:
