Question

How would I order a list so that the list of elements appears in ascending order. I remember it was a simple haskell prelude function but now I forget (:s):

> [1,4,5,7,9,3,1,3,5,1]

[1,1,1,3,3,4,5,5,7,9]

Preferably without having to import modules:

Thanks for reminding me 🙂

Answer 1

Use sort from Data.List to sort your list and then show it. So in a ghci session:

Prelude> :m +Data.List
Prelude Data.List> sort [1,4,5,7,9,3,1,3,5,1]
[1,1,1,3,3,4,5,5,7,9]
