please i need a c++ code for data structure course for pizza managment system by using queue , linked list , stack , oop(polymorphism) please im in hurry.

Here is a data type definition for a list in Haskell: data List a = Empty | One a | Append (List a) (List a) How to make it into an instance of Functor class?

Simple JAVA linkedlist code implementation please help and complete any part you can - Without using the java collections interface (ie do not import java.util.List,LinkedList, Stack, Queue...)- Create an implementation of LinkedList interface- For the implementation create a tester to verify the implementation of thatdata structure performs as expected Build Bus Route – Linked List- Your task is to:o Implement the LinkedList interface (fill out the implementation shell)o Put your implementation through its paces by exercising each of themethods in the test harnesso Create a client (a class with a main) ‘BusClient’ which builds a busroute by performing the following operations on your linked list:o§ Create (insert) 4 stations§ List the stations§ Check if a station is in the list (print result)• Check for a station that exists, and onethat doesn’t§ Remove a station§ List the stations§ Add a station before another station§ List the stations§ Add a station after another station§ Print the…
