If you do not have a certain degree of practice and foundation, it may be very painful to read some books. At this time, we have to stop. If you have

working, but made the code more elusive. 　　6. Success is due to learning in failure; failure is due to error tolerance. There are many programmers who are always defending and saying, "it's normal to make mistakes so hard, and software gets worse ". I have heard a lot about this reason, so we gradually accept these nonsense excuses. But as a

Abstraction is the paradigm of specific examples to a more general context, and abstraction is very important for computer science. Taking our learning function as an example, it is actually observed that some operations are used repeatedly, and we abstract it into a functional module so that it can be called more than
