Subject: New to Programming: Value of gets for just "Enter"

Hello,
I am new to programming in general, and I was having a difficult time
figuring out the solution to this problem as well as thinking of good
key words that would help me find the solution online.

My problem is simply that I do not know what the value of a 'gets' that
doesn't contain anything is. I want this program to end if someone just
hits enter for the gets response, and I don't know how to represent that
in the program itself.

puts 'Enter as many words as you please, one per line. Press enter to
quit.'
array = []
input = gets.chomp.downcase
if input !=  # Not sure what should go here
  while input != # Not sure what should go here
    array.push input.capitalize
    input = gets.chomp.downcase
  end
else
end
puts array.sort

If anyone could help me out with this I would be very grateful. I am
sure there is a very simple solution, but I have been looking around
quite a bit, and have been unable to find anything.

Thanks in advance.
