Nim
This one was pretty simple, just parse the numbers into sets and check the size of the intersection. Part 2 just made the scoring mechanism a little more complicated.
That's some elegant code! Then again, I suppose that's the beauty of nim.
I'm rather spoiled by python, so I feel like it could be more elegant. xD
But yeah, I do like how this one turned out, and nim runs a whole lot faster than python does. I really like nim's "method call syntax". Instead of having methods associated with an individual type, you can just call any procedure as
x.f(remaining_args)to callfwithxas its first argument. Makes it easy to chain procedures. Since nim is strongly typed, it'll know which procedure you mean to use by the signature.Aside from the general conciseness, the "universal function call syntax" is my favorite aspect of nim.
If you want to take chaining procedures to the next level, try a concatenative language like Factor (I have a day 4 solution in this thread -- with no assignment to variables).
I also suggest having a look at Roc if you want a functional programming adventure, which offers great chaining syntax, a very friendly community, and is in an exciting development phase.
Thank you, I'll keep those in mind. Functional programming seems interesting to me, but I don't have any practical experience with it. At some point I want to learn one of the languages that are dedicated to it. Nim does have some features for enabling a functional style, but the overall flexibility of the language probably makes it harder to learn said style.
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !nim@programming.dev
