Environment Requirements

The app must run on:

• Ruby >= 2.2.2
• Feel free to upgrade the ruby version located in Gemfile if you want.
• You will need to install bundler and do a bundle install in the directory to get the required gems installed

Task

You are going to create a Gif pronunciation simulator. To do so, please implement the following methods:

Simulator#initialize(seating_arrangement)

• seating_arrangement is an array of array which represents the people in the initial seating arrangement
• Each element in the inner array is one of: :hard, :soft, or :none

Simulator#verdict

• If the majority of opinionated people think it is a hard g it returns :hard

• If the majority of opinionated people think it is a soft g it returns :soft

• If the opinions are equal then return :push

Simulator#state

• Returns an array of arrays that represents the people in the current seating arrangement

• Each element in the inner array is one of: :hard, :soft, or :none

Simulator#next

• Updates the opinions of all of the people in the seating arrangement based on the rules below

Rules

• If a person with an opinion has fewer than 2 opinionated neighbours then they stop having an opinion since there are not enough people to argue with.

• If a person with an opinion has more than 3 opinionated neighbours then they stop having an opinion since their opinion is drowned out by their neighbours.

• If a person without an opinion has exactly 3 opinionated neighbours and at least 2 of them think "Gif" is pronounced with a hard G then they form an opinion that it is pronounced with a hard G

• If a person without an opinion has exactly 3 opinionated neighbours and at least 2 of them think "Gif" is pronounced with a soft G then they form an opinion that it is pronounced with a soft G

Assumptions

• There will be an NxM seating arrangement
• A neighbour is an adjacent person in the seating arrangement (including diagonals)
• There are hard edges in the seating arrangement (no wrapping around)
• Each person can either think Gif is pronounced with a hard G, a soft G, or they can not have an opinion
• All state transitions happen simultaneously

Tests

• There is a spec (spec/simulator_spec.rb) that outlines some basic scenarios to help you get started. We'd love it if you added some more tests.

• This can be run via bundle exec rspec spec/simulator_spec.rb
