How do you guys feel towards adding some REPL.it links on each problem's description?

For those who aren't familiar with it, it provides an online REPL for most popular languages (Elixir not included 😒), with the option of storing code with a permalink (example).

This functionality would provide an easy and quick platform for testing/debugging/optimization purposes without the hassle of having to set up the language environment.

One of the only downsides I can think of is having to update these snippet links whenever we make changes to our solutions. I don't know if there's a way of loading the code from this repo every time the link is loaded, but that would neatly solve this problem.

Hey guys! It's me again! :)
I've just recently completed the first 50 Euler problems in Elixir. I just wanted to know if I should flood this repo with more Elixir code or not.
I think I recall a Python PR for the first 50 problems being rejected on the grounds of too much code at once, but I can't seem to find it. I did find #2 that included the first 20, though.
Anyways, let me know if it's a good addition! Thanks!

It would be a nice idea if this project has a CONTRIBUTING.md file to guide some newcomers (as me 😁 )

I think on something about this topics:

• Structure of PR naming
• Structure of branch naming (maybe too much?)
• Structure of commit messages in order to create some log of what problems and what language it was solved
• On each PR, create some description to describe your way of thinking (as example, I posted on page 9 on Project Euler forum as user caiangums)

Can we discuss about this?

Would be interesting to see comparisons between different versions automagically.

For example: the current solution to 001 with list comprehensions in contrast to a generator expression

# current
print(sum([n for n in range(1000) if n % 3 == 0 or n % 5 == 0]))

# new
print(sum(n for n in range(1000) if n % 3 == 0 or n % 5 == 0))

Storing a README in each subdirectory with the current stats (cpu time and memory consumption) would be nice.

Hello, Eulerians

We could have a "data science" section in the README (the place doesn't actually matter) to showcase some statistics about the project, such as:

Problems

• How many problems were solved;
• Which problem has the most solutions.

Languages

• How many programming languages;
• Which language has the most solutions;
• Which language has to fastest average time.

Something along these lines.
Does that sound nice to you people? Any other suggestions?

There's a lot of problems in Project Euler that relies on the same kind of operations, e.g., prime testing, prime generator, fibonacci sequence, and so on. It would be nice to have these kind of functions in file shared by all solutions as a lib.

What you guys think about that?

Can be rewritten as:

object P1 extends App {
  println((0 to 999).count(x => Seq(3, 5).exists(x % _ == 0)))
}

Hey guys, I've just opened #33 which consists of the elixir solution for problem 145.
Unfortunately it is very badly optimized for now, taking 30 min to compute.
If anybody has any suggestion for improvement, I'd be happy to test it out! 😄
Thanks!
