99 bottles

# Iterative solution
# 
bottles = (0..99).to_a

bottles.reverse.each do |bottle|
  if bottle.zero?
    puts "#{bottle} bottles of beer on the wall. No more beer"
  else
    puts "#{bottle} bottles of beer on the wall.."
  end
end

# Looping solution
# 
bottles = 99
until bottles.zero? # you could also write: while bottles != 0
  puts "#{bottles} bottles of beer on the wall.."
  bottles = bottles - 1     # you could also use a shorthand: bottles -= 1
end

puts "#{bottles} bottles of beer on the wall. No more beer"
