You are encouraged to solve this task according to the task description, using any language you may know.
Two or more words can be composed of the same characters, but in a different order. Using the word list at http://www.puzzlers.org/pub/wordlists/unixdict.txt, find the sets of words that share the same characters that contain the most words in them.
Haskell
import Data.List groupon f x y = (f x) == (f y) main = do f <- readFile "./../Puzzels/Rosetta/unixdict.txt" let words = lines f wix = groupBy (groupon fst) . sort $ zipWith ((,).sort) words [0..] mxl = foldl' ((.length).max) 0 wix print . map (map ((words!!).snd)) . filter ((==mxl).length) $ wix
