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

If the real string you are comparing are similar to the strings you provided, then this should work:

teamOneArr = teamOne.split(", ")
=> ["Billy", "Frankie", Stevie", "John"]
teamTwoArr = teamTwo.split(", ")
=> ["Billy", "Frankie", Stevie"]
teamOneArr - teamTwoArr
=> ["John"]
