Is there an easy way to change [Int] -> String ?
My output function returns a list of int but the format should be a string as in the example below
example: [1,2,3,4] -> 1 2 3 4

@PRVS That one does more work, also involving non-base-10 representations. – chi Mar 04 '16 at 10:09

What do you mean with *change*? – Willem Van Onsem Mar 04 '16 at 10:14

To turn an integer into a string, use show.
To turn a list of integers into a list of strings, use map show.
To add " " between every string in a list of strings, use intersperse " ". (Requires import Data.List)
To concatenate a list of strings, use concat.
Alternative: try unwords ["a","b","c"] in GHCi.

Thanks, that's exactly what I needed. I was unsure what to do after map show, but you made it clear enough. Thumbs up! – Marc Zaharescu Mar 04 '16 at 10:17
