pythonchallenge.com 4在红宝石溶液中

问题描述

比下面的ruby代码，是否有一个“更好/替代/更具可读性”的解决方案来http://www.pythonchallenge.com/pc/def/linkedlist.php？ 我能理解，但对我来说似乎不太清楚...

#!/usr/bin/env ruby -w
# encoding: utf-8

require \'net/http\'

Net::HTTP.start \'www.pythonchallenge.com\' do |http|
  nothing = 12345

  nothing = case http.get(\"/pc/def/linkedlist.php?nothing=#{nothing}\").body
    when /(\\d+)$/ then $1.to_i
    when /by two/ then nothing / 2
    when /\\.html/ then puts $`
  end while nothing
end

    

解决方法

        没关系，但让我们尝试使其更具可读性：

#!/usr/bin/env ruby -w
# encoding: utf-8

require \'net/http\'

Net::HTTP.start \'www.pythonchallenge.com\' do |http|
  next_one = 12345

  while next_one
    response = http.get(\"/pc/def/linkedlist.php?nothing=#{next_one}\").body

    case response 
      when /Divide by two and keep going./ then
        next_one = next_one / 2
      when /and the next nothing is (\\d+)/ then
        next_one = $1.to_i
      else
        puts \"Solution url: www.pythonchallenge.com/pc/def/linkedlist.php?nothing=#{next_one}\"
        next_one = false
    end
  end

end
