First, put out your own code.

Two. Ideas

1. The first response to the experiment was to read the document, and then, without much thought, to go ahead and get the papers.

2. After the document is finished, think about it. symbol is removed, and then all the words are integrated together

3. Finally, the method is used for statistics
