1. Write a Ruby class that represents an Item ordered by a customer. The attributes include

item id, item name, item price, item count and total price. The class should include the

Ruby builtin mixin Comparable, so that Items in a list can be sorted by item count in

descending order, followed by total price in descending order, followed by item name in

alphabetic order. Documentation for Comparable can found at https://rubyapi.org/2.6/o/

comparable.
