Im assuming the elements in the array are strings so.....

so we have arr1 and arr2 with the previous mentioned elements i guess
you could make a method something like this and then depending on how
your comparing these elements...

def print_elements_not_in_array
  arr1.each do |temp|
    arr2.each do |temp2|
      puts " #{temp2} " if temp1 != temp2
    end
  end
end
