Primes
kactl
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- Is this an efficient way to check if a number is prime number?
- I need some help on a project!!!

Has anyone solved the prime number problem on SPOJ yet using pure python?
Take a look at Dave Plummer’s Prime Sieve project.

Zig wins Dave Plummer's prime sieve benchmark ... but via a problematic metric
There's a dedicated and quite cool website where you can browse the benchmark results: https://github.com/PlummersSoftwareLLC/Primes
- Since when did Python haters spread out everywhere? Maybe DNF5 would be faster because of ditched it, maybe.
- creating a vec takes forever?

Python vs. Nodejs vs. Lua
Should look into Software Drag Racing https://github.com/PlummersSoftwareLLC/Primes

We wouldn’t even consider writing back-end code for a website CMS in anything other than C, and we certainly wouldn’t use any of the interpreted languages that have sprung up in the last couple of decades and positioned themselves as the de facto go-to standards for web development.
Compiler WTF??? Can't you just use xxd to turn a hexdump into a binary like a real programmer would do?!?

As a competitive programmer, I’ve seen similar ‘magic’ tricks here: https://github.com/kth-competitive-programming/kactl/blob/ma... (page 23)

Learning Python was a good decision. Python may have its own shortcomings, but big integers aren't scary anymore 😇😇
Printed references (e.g. KACTL) are allowed.

Competitive Programming Is Useless
There's not _that_ many algorithms or data structures you see in competitive programming, and the vast majority of them aren't advanced. You do need to memorize a good portion of them, but doing so is the easy part towards becoming good at it.
You can read one moderate length book and know all of the DSes and algorithms you'll need for 99.9% of the time. cses.fi/book is a good one with a free version if you're curious.
https://github.com/kth-competitive-programming/kactl may also be of interest, it contains a good amount of the algorithms/DSes you'd ever need on a few printable pages (20ish).

I want to design and build a programming language specifically for competitive programming!
Finally, there are certain types of algorithms/operations that can be very sensitive to implementation. For example, a "good" Fast Fourier Transform implementation may be 3-4 orders of magnitude faster than a naive recursive one (with the same complexity!). Another fun case is something like (a*b)%c when the numbers are 64 bit. Using a fast implementation like this one (https://github.com/kth-competitive-programming/kactl/blob/master/content/number-theory/ModMulLL.h#L20) can speed up your code by 3-4x compared to using a naive implementation.
