Chinese is called function, which is just a matter of translation. Look at the English function, which is actually a function, a function. In the process of solving a problem, programming and mathematics are actually different. Mathematics allows you to turn a description into a formula to calculate. Programming is equivalent to a calculator. The calculator can't get the formula directly from the problem description, but it will help you calculate after you turn the problem into a mathematical problem.

A person who is good at math may not be good at programming, but an excellent programmer is not bad at math. You can look at some programming contest topics, such as acm, which is actually a math problem and also requires your programming ability.

I hope it helps you.
