> ## Price Ranges
>
> _Quiz description by James Edward Gray II_

> You have a list of price ranges from different vendors like:
>
>     Company A:  $1,000 - $3,000
>     Company B:  $6,000 - $10,000
>     Company C:  $500 - $2,500
>
> Given such a list and the desired price range a shopper wishes to pay,
> return the companies the shopper should examine. For example, if the
> shopper's price range was:
>
>     Low:   $2,500
>     High:  $5,000
>
> the companies returned would be:
>
>     Company A
>     Company C
>
> The shopper should also be allowed to provide just a low or just a high
> value instead of both, should they prefer to do so.
