Algorithms

Learning outcomes

  • Understand design by contract
  • Understand algorithm names increase expressiveness of code
  • Understand difference between if and assert in function writing

Intro

How do I write functions [1] that are:

  • easy to use
  • correct
  • fast [2]

References;

  • [1] For now, we use algorithm == function, as the definition of an algorithm is 'a step-by-step procedure for solving a problem or accomplishing some end' @dictionary_algorithm

  • [2] pick any vague definition

  • Function design

  • assert
  • Recursive algorithms

Discuss

  • Function design is hard
  • Documentation helps
  • TDD helps
  • assert helps
