Ruby Challenge: State Counts

Goal

You are given an array of struct-like records with these attributes:

• state The name or short abbreviation of a state/province
• country The name or short abbreviation of a country
• count A number representing some data for this location

The input strings representing the state and country are ill-defined. But, we have a master list of states and countries that we want to match them to.

For convenience you are given some defined constants for the master data like CA_BC (BC, Canada) or US_CA (California, USA) with these attributes:

• name Full name like "British Columbia"
• iso A 2-character code like "BC"
• fips A state-country code like "BC.CA"
• country A reference to a country object

The country objects have the following attributes available:

• name Full name like "Canada"
• iso A 2-character code like "CA"
• iso3 A 3-character code like "CAN"

The goal is to match up the example input to our master data and produce a hash that looks like this:

{
  CA_BC => 123,
  US_CA => 456,
  # ...
}

Process

Run rspec spec and implement a solution for the failing spec. You may add your own specs for any of your own code, but changing the example specs is off-side.

Example input data can be found in the specs.

Master location data is provided in master_data.rb
