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

easy solution:

 def compare(a, b)
   diff = a.split(', ') - b.split(', ')
   if diff === [] // a and b are the same
     true
   else
     diff
   end
 end

of course this only works if your strings contain comma-separated values, but this can be adjusted to your situation.
