I asked everyone, and they said that data structures and discrete mathematics are useful (especially data structures) .H

In fact, most people's work will not directly use the knowledge of courses such as mathematical analysis, mathematical logic, probability statistics, linear algebra, and discrete mathematics, but these courses (especially mathematical analysis) are very good for training people's logical thinking skills. And thoughtfulness
These capabilities are too useful in the IT industry.

But I can’t figure out why LZ doesn’t use data structures, and I still use a lot when I write programs.

For Afghanistan, even writing web programs javascirpt requires knowledge of data structures, such as directory trees.

If you want to achieve any level of directory tree in vc, what pre-order, middle-order, post-order, etc. should also be needed.

The data structure is not used, I don't think it can be called a programmer.

I've done a directory tree after querying the database, but they are all called recursively. How can I use pre-order, middle-order and post-order?

Recursion and X order traversal, many things are the same result.

It’s useless. I said it’s useless...

Isn't binary tree a typical recursive application?

Use more data structures
