| -- Given this in Lisp: | |
| -- (defn eddington [a] (count (filter true? (keep-indexed < (reverse (sort a)))))) | |
| -- do it in Haskell (thanks to @zimpenfish for the original) | |
| import Data.List | |
| -- keep-indexed f l applies f over l and keeps the result of anything that is | |
| -- not nil. f takes two arguments, index of list item and list item | |
| -- We can do this in Haskell by zipping the original list with the indices |
