Hello,
I need to make a sort of loop so a text is displayed several times.
So this idea :
repeat 3 true will be True True True.
So in another language I would have programmed.
for teller = 1 to a
print text
But I need to use list comprehession.
So I thougt I use this :
replicate :: Int -> a -> [a]
replicate a xs = [xs | x' <= a <-xs]
But now I get this message :
oefening.hs:2:24: Parse error in pattern: x' <= a
Where did I go wrong here ?
