splitWith' :: (a -> Bool) -> [a] -> [[a]]
splitWith' p x = case takeUntil p x of
 -> 
x' -> subset : splitWith' p x''
where (subset, x'') = break p x'
where takeUntil :: (a -> Bool) -> [a] -> [a]
takeUntil p' = takeWhile q
where q x = not (p' x)
It doesn't give me the right behavior though.
It should work like this:
splitWith' odd [2,2,1,4,4,3,6,6,5]
but it works like this instead
I'm pretty sure I modeled splitWith' on words, which is what the
exercise indirectly suggests.
Can someone help me step through this code to figure out what's wrong.
It looks right to me.
