This is haskell and how to do tolist and from list?

PART 1. You need to define a Set datatype. Below is an example which uses 11sts internally. It is here as a guide, but also to stop ghei complaining when you load the file. Free free to change it. 3 - you may change this to your own data type newtype Set a = Set { unSet : : [a] } \{- PART 2. If you do nothing else, at least get the following two functions working. They are required for testing purposes. 3 tolist {2,1,4,3}[1,2,3,4] .- the output must be sorted. tolist :: Set a [a] tolist = undefined fromList [2,1,1,4,5]{2,1,4,5} fromList :: ord a [a] Set a fromList = undefined
