1. Look at the array_2_hash method in the lib/hashes.rb file.

You will notice that this method takes two inputs.

emails: an array of email addresses of type string. Example: ["bobsmith@example.com"]

contacts: a hash for contacts. The keys for this hash will be the contact names as type string and the values will be the contact email addresses as type strings. Example: {"Bob Smith":"bobsmith@example.com"}

Assumptions: The array and hash both contain the same number of items and will be already in the correct order.

Hint: Look at the rspec tests to see the inputs that will be tested.

Write the Ruby code in this method that will return the contacts hash with emails populated from the array.

Run rspec in the terminal window to test. Once everything is passing, upload your screenshot to this question.

RSpec.configure do |config|
