ruby - 前面大写单词的方法

Question

我正在尝试将大写单词移到句子的前面。我希望得到这个:

capsort(["a", "This", "test.", "Is"])
#=> ["This", "Is", "a", "test."]
capsort(["to", "return", "I" , "something", "Want", "It", "like", "this."])
#=> ["I", "Want", "It", "to", "return", "something", "like", "this."]

关键是保持词序。

我觉得我很亲近。

def capsort(words)
  array_cap = []
  array_lowcase = []
  words.each { |x| x.start_with? ~/[A-Z]/ ? array_cap.push(x) : array_lowcase.push(x) }
  words= array_cap << array_lowcase
end

很想知道其他优雅的解决方案可能是什么。

Answer 1

问题被彻底改变了，使我之前的回答完全错误。现在，答案是:

def capsort(strings)
  strings.partition(&/\p{Upper}/.method(:match)).flatten
end

capsort(["a", "This", "test.", "Is"])
# => ["This", "Is", "a", "test."]

我之前的回答是:

def capsort(strings)
  strings.sort
end

capsort(["a", "This", "test.", "Is"])
# => ["Is", "This", "a", "test."]

'Z' < 'a' # => true , 没有什么可做的。
