advent-of-code-2020 VS dmoj-rust

Another brilliant source which I've found is https://github.com/timvisee/advent-of-code-2020. Great inspirational use of iterators there.

Cool to see the itertools approach here though :) Link to the solution I saw before

Cool! My first time on TWIR with Solving Advent of Code 2020 in under a second. Though it isn't specifically about Rust, I did use Rust.

The use of a different data structure for the low and high side of the look up table made it faster as described here.

Oh yes, did Advent of Code in under a second last december, shameless plug 😎.

sign up for an account on dmoj.ca or similiar online judge website and do the problems there. they have ccc problems and waaay more that you can get your solutions judged instantly.

DMOJ - Modern Online Judge - contest platform and archive of programming problems.

I can't suggest this enough times but https://dmoj.ca/ is the best resource I've found for practice questions. It has past coding competition problems on there that range vastly in difficulty. You'll need to make an account to get started but it's really worth it. I suggest to start off with problems that are 1-3 points, then go up once you feel more confident. It's a really great site, much better than finding your own coding problems since they have online judges that can run test cases for you.

https://dmoj.ca/ thousands of problems for competitive coding; not just Python. Once you've successfully solved a problem, you then have access to everyone else's responses. Definitely learned a lot from seeing how others write their code.

Hello, my name is Kevin, 15, from Canada. I have been learning cp for about 2 years now. My level in cp is about candidate master to master on https://dmoj.ca/ . I am currently preparing for Canada’s computing competition. I would love to have someone to ask questions to and discuss problems with. Thank you

DMOJ (DMOJ Modern Online Judge) is a Canadian platform for competitive programming, mostly geared towards high school students.

I started out watching Lua video tutorial (linked below) then I did exercises for about a week on sites like https://exercism.io/ or https://dmoj.ca/

Nice! I had a similar experience when I tried it out for competitive programming on dmoj, particularly because they made a crate for faster input. Usually the performance is similar to c or c++, but sometimes I'd write the exact same code for both and rust would be faster for whatever reason. Plus, rust has always been easier to debug for me.
