Use TDD to create an Exhibit and a Patron class that respond to the following interaction pattern:
pry(main)> require './lib/exhibit'
# => true
pry(main)> require './lib/patron'
# => true
pry(main)> exhibit = Exhibit.new({name: "Gems and Minerals", cost: 0})
# => #<Exhibit:0x00007fcb13bd22d0...>
pry(main)> exhibit.name
# => "Gems and Minerals"
pry(main)> exhibit.cost
# => 0
pry(main)> patron_1 = Patron.new("Bob", 20)
# => #<Patron:0x00007fcb13b5c7d8...>
pry(main)> patron_1.name

pry(main)> patron_1.interests
# => ["Dead Sea Scrolls", "Gems and Minerals"]Use TDD to create a Museum class that responds to the following interaction pattern. For the recommend_exhibits method, the Museum should recommend exhibits that match a Patron's interests.

- For
patrons_by_exhibit_interest, this method takes no arguments and returns a Hash where each key is an Exhibit. The value associated with that Exhibit is an Array of all the Patrons that have an interest in that exhibit. ticket_lottery_contestantsreturns an array of patrons that do not have enough money to see an exhibit, but are interested in that exhibit. The lottery winner is generated randomly based on the available contestants whendraw_lottery_winneris called.- You will need to use a stub to test the
announce_lottery_winnermethod in conjunction with thedraw_lottery_winnermethod. JOY!

- When a
Patronis admitted to theMuseum, they attendExhibits. TheExhibitsthat aPatronattends follows these rules: - A Patron will only attend
Exhibitsthey are interested in - A Patron will attend an
Exhibitwith a higher cost before anExhibitwith a lower cost. - If a
Patrondoes not have enoughspending_moneyto cover the cost of theExhbit, they will not attend theExhibit. - When the Patron attends an
Exhibit, the cost of theExhibitshould be subtracted from theirspending_moneyand added to theMuseumrevenue. - A
Museumshould have apatrons_of_exhibitsmethod that returns a Hash where the keys are the exhibits and the values are Arrays containing all thePatronsthat attended thatExhibit. - A
Museumshould have a methodrevenuethat returns an Integer representing the revenue collected fromPatronsattendingExhibits.
The Museum class should respond to the following interaction pattern:
