title: Finding the difference between strings in Ruby
body: <p>I need to take two strings, compare them, and print the difference between them.</p>
  
  <p>So say I have:</p>
  
  <pre><code>teamOne = "Billy, Frankie, Stevie, John"
  teamTwo = "Billy, Frankie, Stevie"
  
  $ teamOne.eql? teamTwo 
  =&gt; false
  </code></pre>
  
  <p>I want to say "If the two strings are not equal, print whatever it is that is different between them. In this case, I'm just looking to print "John."</p>
