Sam is a picky eater. He will only eat pizza that haves pineapple, tuna, or both mushrooms and ham, but he will defuse to eat any pizza that haves pepperoni or tomato sauce. Assume you have a function "contains" that can tell you if the pizza have a certain ingredient: for instance , you would write "contains(mozzarella)" to check if the pizza has mozzarella.
Write a predicate (condition) that returns "true" if Sam will eat the pizza and "false" if Sam will defuse it.
