ruby - Method to front capitalized words -

i trying move capitalized words front of sentence. expect this:

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."] 

the key maintaining word order.

i feel i'm close.

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 

curious see other elegant solutions might be.

def capsort(words)   words.partition{|s| s =~ /\a[a-z]/}.flatten end  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."]
