#以下為 Array 應用 
#使用者輸入
puts "Hi, please enter a sentence."
sentence = gets.chomp

#分拆句子結構 (拆字串&序號)
sentence_split = sentence.split(" ")
sentence_index = (0..sentence_split.length-1).to_a

#取得每項字母長度
word_length = []
sentence_index.each do |i|
  word_length.push (sentence_split[i].length)
end

#若字母數為奇數，則印出字母數；否則，顛倒字序
reverse = []
sentence_index.each do |i|
  if word_length[i] % 2 == 1
    reverse.push(word_length[i])
  else
    reverse.push(sentence_split[i].reverse)
  end
end
