Only Allowed Toppings

The picky pizza oven has an allowed-toppings list, and it rejects any order containing something else. 🍕

You get the allowed toppings and the customer's order. Print order accepted if every ordered topping is allowed, or not on the menu.

Example:

Input: allowed = ["cheese", "olive", "corn", "basil"], order = ["corn", "cheese"] Output: order accepted

Every ordered topping ("corn", "cheese") is inside the allowed set, so the order set is a subset.

Input: allowed = ["cheese", "olive"], order = ["cheese", "pineapple"] Output: not on the menu

"pineapple" isn't in the allowed set, so the order set isn't a subset.
