PROGRAMMING IN HASKELL Chapter 10 – Interactive Programming 0 Introduction To date, we have seen how Haskell can be used to write batch programs that take all their inputs at the start and give all their outputs at the end. batch program inputs outputs 1 However, we would also like to use Haskell to write […]

{- This Haskell program converts an md file to an hs by removing everything that is not Haskell code. * Lines between ““`haskell” and ““`” are copied. * However, lines between ““`hs” and ““`” are not copied, deliberately. This is to be able to control what to copy or not, while still retaining syntax highlighting

# Activity Plan for Week 3 ## Summary In Week 3 of the Functional Programming module, we will: 1. study the list comprehensions and see how these could be used/reused for generating lists of values 2. study recursion and understand how functions could be defined in terms of themselves – a more natural way of
