推荐答案

问题出在哪里?

Where is your problem?

1. 从页面中读取项目
2. 记住当前拥有的项目列表.
3. 从页面中读取下一个项目列表(新列表)时，请查看哪些项目不是
4. 在原始列表中浏览并尝试在新列表中查找每个项目.如果不存在，则该项目为已删除项目.

1. Read the items from the page
2. Remember the current list of items you have.
3. When reading the next item list (new list) from the page see which items are not yet in the original list as these are the new ones.
4. Go through the original list and try to find each item in the new list. If it is not there then that item is a deleted item.

瞧，任务完成了！
