  19. def unfoldLeft [A, B] (seed: B)(f: (B) ⇒ Option[(B, A)]): Seq[A]

    Produces a Seq from a seed and a function.

    Produces a Seq from a seed and a function.

    Example, produces a List from 0 to 100.

    unfoldLeft(0) { state match
      case a if a > 100 => None

    A

    Type of the final List elements.

    B

    Seed type

    seed

    Initial value.

    f
