3. Remove the , :disabled => true from the hash_2_array collection in the spec/hashes_spec.rb file. Don't forget to save your changes!

Now look at the hash_2_array method in the lib/hashes.rb file.

You will notice that this method takes one input.

contacts: a hash for contacts. The keys for this hash will be the contact names as type string and the values will be an inner hash that will hold the email address (with "email" as key) as type string and phone number (with "phone" as key) as type string.

Example:

{:"Bob Smith"=>{:email=>"bobsmith@example.com", :phone=>"555-555-5555"}

Hint: Look at the rspec tests to see the input that will be tested and the expected output.

Write the Ruby code in this method that will create three arrays of type string from the hash and then will return an array that contains these three arrays (a two dimensional array!).

Assumption: Your returned array will contain the inner arrays in the following order: emails, phones, names.

Example:

[["bobsmith@example.com"],["555-555-5555"],["Bob Smith"]]

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