linerFind :: [Int] -> Int -> MaxSA -> MaxSA --MaxSA is MaximumSubarray
linerFind xs len ms1@(MaxSA l h m) -- (MaxSA leftPosition rightPosition maxsum)
| h<len = keepFind ms1
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
