a parse error....i can't fix it
sorry and please forget the name and what it is meaning for.
just look at in syntax aspect
the error : "parse error on input `|'
Failed, modules loaded: none."
linerFind :: [Int] -> Int -> MaxSA -> MaxSA --MaxSA is MaximumSubarray
linerFind xs len ms1@(MaxSA l h m) -- (MaxSA leftPosition rightPosition maxsum)

where keepFind ms'@(MaxSA l' h' m')= let ms2@(MaxSA l2 h2 m2)= find' xs l' (h'+1) in if m < m2 then linerFind xs len ms2 else keepFind ms2
|otherwise = ms1 --compiler say |error is in this line
You must have the where clause after the guards, linerFind ... | h < len = keepFind ms1 | otherwise = ms1 where ...
Formatted in this way should be compile:
linerFind :: [Int] -> Int -> MaxSA -> MaxSA --MaxSA is MaximumSubarray
linerFind xs len ms1@(MaxSA l h m) -- (MaxSA leftPosition rightPosition maxsum)
