iterateMutableN :: (Contiguous arr, Element arr a, PrimMonad m) => Int -> (a -> a) -> a -> m (Mutable arr (PrimState m) a)

contiguous Data.Primitive.Contiguous

Apply a function n times to a value and construct a mutable array where each consecutive element is the result of an additional application of this function. The zeroth element is the original value.

iterateMutableNM :: (Contiguous arr, Element arr a, PrimMonad m) => Int -> (a -> m a) -> a -> m (Mutable arr (PrimState m) a)

contiguous Data.Primitive.Contiguous

Apply a monadic function n times to a value and construct a mutable array where each consecutive element is the result of an additional application of this function. The zeroth element is the original value.
