What are the methods of counting prime numbers.
The first idea that came to my mind is matrices, but I don't know if that is the right direction.
Are there any tested libraries for counting prime numbers?

What I have tried:

I was looking for solutions on the internet, but the more I read, the less I know :(

There are infinite prime numbers.

I know what prime numbers are. I mean code implementation. Should you do everything yourself from the beginning or are there any ready-made solutions?

It's good if they were on matrices, but I will also see others.

No, it's a popular beginning programming assignment.
And it's fun.

As far as I know, counting prime numbers is not a subject such as one have created a library on this subject.

I have no idea how counting prime cumbers is related to matrices.

The subject is so basic, that it is just about detecting prime numbers in given range, and counting them. After that, the difference between methods are how clever they are, how they avoid useless work.

## Solution 3

Prime counting does not involve matrices.

Everything there is to know about the subject is available in this Wikipedia article:
Prime-counting function - Wikipedia[^].
