You are doing set operations, so I looked there first:
require 'set'
s1 =3D Set.new [1, 2, 7, 8, 9, 45, 98, 85, 39]  =20
s2 =3D Set.new [1, 45, 66, 4, 84, 98 ]

p (s1 - s2) | (s2 - s1)

Hey, I just have a quick question about arrays.

I have two different ones that I would like to compare.

Example:

Array 1: cats, dogs, monkeys

Array 2: cats, fish, dogs, birds, monkeys

Now, I would like to compare array 2 with array 1 and have it spit out
any words that aren't in both... if that makes sense.

So what the program should output is fish, monkeys.
