I used to be a computer major, and now I have been working for several years! It's really hard to say how helpful mathematics is to programming, because there are really no programming problems at work, or that the algorithm is solved by a mathematical formula, hehe! According to my own understanding, the main function of mathematics is to cultivate people's thinking ability, which is subtle. Only when you study hard and study hard can you feel its role. You should treat the basic courses in school well, such as compilation principle, microcomputer principle and even assembly, which are rarely used after work, but you should study hard. They cultivate your computer thinking! It's really practical. It's for work and it's not too late to study after work. The school still has to learn the basic courses well and find a job just after graduation. No one will ask you about the project, how to use it actually, that is, big companies interview fresh graduates and interview your teaching materials!
