II. Objectives

Statistics in Journey to the West:

1. How many different Chinese characters have appeared?

two。 How many times does each Chinese character appear?

3. Which Chinese characters appear most frequently?

Third, the content involved:

1. Read the file

two。 Use of dictionaries

3. The ordering of dictionaries

4. Write a file

IV. Effect

5. Source code
