Finding the difference between strings in Ruby

Question

I need to take two strings, compare them, and print the difference between them.

So say I have:

teamOne = \"Billy, Frankie, Stevie, John\"
teamTwo = \"Bi         


        

Answer 1

I understood the question in two ways. In case you wanted to do a string difference (word by word) which covers this case:

teamOne = "Billy, Frankie, Tom, Stevie, John"
teamTwo = "Billy, Frankie, Stevie, Tom, Zach"

s1 = teamOne.split(' ')
s2 = teamTwo.split(' ')

diff = []
s1.zip(s2).each do |s1, s2|
  if s1 != s2
    diff << s1
  end
end

puts diff.join(' ')

Result is:

Tom, Stevie, John

Accepted answer gives:
