mission details
The task of this level: write a system that uses production methods to identify animals.
Programming requirements
According to the prompts, add code in the editor on the right to complete the operation of the production system-animal identification system, and finally achieve the result of inputting animal characteristics and outputting animal type.
Special Note
In this experiment, there is an experimental phenomenon, that is, your self-test run output result is exactly the same as the experiment required output result and it cannot pass. Why?
Answer: I don’t know if this is a bug in the Touge experimental platform. Generally, when we write program code, the format is required to be in English format, but in this experimental test, the punctuation mark is in Chinese and English format if it fails. As shown in the picture:
The first place:
The second place: The format of the commas " , "
marked in the picture is Chinese format, otherwise it will not pass (if the bug is fixed, there will be no problem).
