推荐答案

我们不会为您做功课，但是我会给您一些指导. > 1)阅读时，您需要一个收集对象来将单词放入.
2)在将找到的单词实际插入到集合中之前，您需要确保该单词在集合中不存在. (提示:为此使用集合的内置方法)

We''re not going to do your homework for you, but I will give you some pointers.
1) You''ll need a collection object to put the words into as you read them.
2) Before you actually insert a found word into the collection, you''ll need to make sure that the word doesn''t already exist in the collection. (Hint: Use a built in method of the collection for this)
