# The IP. In this example we'll get it from the environment
ip = ARGV[0]
# First, let's split the IP into octets and map them to integers
ip = ip.split(".").map(&:to_i)
# Now that's done, let's loop through each octet
ip.each do |octet|
  # Check if the length of the integer is still more than 1 AND the first character in the octet is 0
  while octet.digits.count > 1 && octet[0] == '0' do
    # Strip the 0 out
    octet[0] == ''
  end
end
# Last couple of things. First reassemble the array of octets into the IP again
ip = ip.join(".")
# Finally, let's output said IP
puts ip
