Each_with_index

Hi, I'm trying to get my file to take in a list of names (a firstname,
surname and middlename) and to then list each part of the name with an
index. For example one name "John, Smith, Paul" should be printed as
1.John
2.Smith
3.Paul

I can list the index as 1.John Smith Paul but am unsure on how to list
each part of the name seperately, does anyone have any ideas?

Create one array with all the strings in it. Or define Person#each or
Person#to_a.

Best,

"John, Smith, Paul".split(", ").each_with_index do |name, index|
  puts "#{index + 1}. #{name}\n"
end
