标题: [练习] 寻找单词

给定一个输入的字符串和
一个包含各种单词的字典，
用空格将字符串分割成一系列字典中存在的单词。

example: 字典

WORDS = %w[
100 200 ARG Linux Note To UNIX a an and apple as
available between command commend contains delimited
dict dictionary each elect file generate input is
like line list newline numbers of on operating options
permutations random select sentence sentences sep
separate share shuf shuffle standard system the
treat usr with words
]

字符串:
sentenceselect
Toshufflethenumbersbetween100and200

那么我们应该得到:
["sentence", "select"] ["sentences", "elect"]
["To", "shuffle", "the", "numbers", "between", "100", "and", "200"]

这种单词分割很不好处理啊。

#!/usr/bin/env ruby

WORDS = %w[
100 200 ARG Linux Note To UNIX a an and apple as
available between command commend contains delimited
dict dictionary each elect file generate input is
like line list newline numbers of on operating options
permutations random select sentence sentences sep
separate share shuf shuffle standard system the
treat usr with words
]

start = 0
str='sentenceselect'
str='Toshufflethenumbersbetween100and200'
length = str.length
w=[]
(start..length).each do |s|
        (s+1..length).each do |x|
           tmp_word=str[s...x]
           w.push(tmp_word) if WORDS.count(tmp_word) > 0
        end
end

puts w.inspect()

#!/usr/bin/env ruby
WORDS = %q[
100 200 ARG Linux Note To UNIX a an and apple as
available between command commend contains delimited
dict dictionary each elect file generate input is
like line list newline numbers of on operating options
permutations random select sentence sentences sep
separate share shuf shuffle standard system the
treat usr with words
]
Subwords=WORDS.split

spec=[]
string1="sentenceselect"
string2="Toshufflethenumbersbetween100and200"
Subwords.each do |words| if string1=~/#{words}/ or string2=~/#{words}/
       spec<< words if !spec.include?("#{words}")
end
end
puts spec

执行结果：
100
200
To
a
an
and
between
elect
numbers
select
sentence
sentences
shuf
shuffle
the
稍微改动了点，初学者，不知道这个符不符合要求？
