:: (a -> a -> Ordering) -> [a] -> a package:vector

O(n) Yield the maximum element of the vector according to the given comparison function. The vector may not be empty. In case of a tie, the first occurrence wins. This behavior is different from maximumBy which returns the last tie.

Examples

>>> import Data.Ord

>>> import qualified Data.Vector.Strict as V

>>> V.maximumBy (comparing fst) $ V.fromList [(2,'a'), (1,'b')]
(2,'a')

>>> V.maximumBy (comparing fst) $ V.fromList [(1,'a'), (1,'b')]
(1,'a')

O(n) Yield the minimum element of the vector according to the given comparison function. The vector may not be empty. In case of a tie, the first occurrence wins.

Examples

>>> import Data.Ord

>>> import qualified Data.Vector.Strict as V

>>> V.minimumBy (comparing fst) $ V.fromList [(2,'a'), (1,'b')]
(1,'b')

>>> V.minimumBy (comparing fst) $ V.fromList [(1,'a'), (1,'b')]
(1,'a')
