groupBy package:vector

O(n) Split a vector into a list of slices, using a predicate function. The concatenation of this list of slices is equal to the argument vector, and each slice contains only equal elements, as determined by the equality predicate function. Does not fuse.

>>> import qualified Data.Vector as V

>>> import           Data.Char (isUpper)

>>> V.groupBy (\a b -> isUpper a == isUpper b) (V.fromList "Mississippi River")
["M","ississippi ","R","iver"]

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