Those so-called great gods will only sneer at novices. Even if you learn this, this and you don't know that, it's no use. Even if you have learned it, it is useless if you are not from an ordinary class. Even if you come from an ordinary class and learn algorithms well, you can't do without poor communication skills.

To sum up, they will just sit still and watch how beginners have no direction when they first get started, and they are at a loss in the face of various new technologies. They will only tell you that everything you do is wrong, but they won't tell you what is right.

Upstairs said, if the algorithm can be remedied by going to cram school, and there is no self-learning ability, don't be a programmer. Does that mean that programmers have to teach themselves without teachers? Does that mean there is no difference between ordinary classes and non-ordinary classes? Anyway, they are all self-taught? So if some people, after taking your advice, don't apply for that class and finally get lost in the interview, many details should have been noticed in this course, will you be responsible?

I really hate people who pretend to be lofty and think how great they are. Newcomers ask some "stupid" questions and make all kinds of attacks. If you don't know how to help others improve, please don't just criticize. If there is no solution to the problem, or you don't even know the answer, there is no need to ask it to show how tall you are.
