[練習] 尋找單詞

rubyish

給定一個輸入的字符串和
一個包含各種單詞的字典，
用空格將字符串分割成一系列字典中存在的單詞。

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

那么我們應該得到:
["sentence", "select"] ["sentences", "elect"]
["To", "shuffle", "the", "numbers", "between", "100", "and", "200"]

ddd010

這種單詞分割很不好處理啊。

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()

Subwords=WORDS.split

spec=[]

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

執(zhí)行結果：
100
200
To
a
an
and
between
elect
numbers
select
sentence
sentences
shuf
shuffle
the
稍微改動了點，初學者，不知道這個符不符合要求？
