给出任意多个有 5 个元素的数组，如 [[10, 32, 43, 11, 4], [7, 36, 44, 9, 4], ...]，数组各项合计为 100 ，如何根据和指定数组 [1, 32, 48, 17, 2] 的相似度进行排序？最好是计算每项的相似分值，然后按分值排序。

def random_distribution(size = 5)
  a = []
  (size - 1).times do |i|
    s = a.inject(&:+) || 0
    a << rand(100-s)
 end

$ gem install htmlentities
$ echo -n '测试文本' | ruby -r htmlentities -e "puts HTMLEntities.new.encode(STDIN.read, :decimal)"
