Made a 3blue1brown-style animation exploring the solution to one of my favorite problems!
By kazamasmile, history, 2 years ago, In English

I'm now running a Youtube channel dedicated to teaching algorithmic thinking and sharing the joy of competitive programming through animation.

I'd be honored if you could take a look at our first project, which just released a few days ago!

I recognize there's ample room for improvement, so any constructive feedback is appreciated!

Thanks so much everyone :)

Here's the video!

Amazing effort! One of the best and most educational video on a cp problem i've seen.

Nice work. I must ask, is it efficient? How much time it took you to make this video?

    Actually it took quite a long time, but a lot of that was learning the animation library too. Around 1.5 months of effort, maybe 60-ish hours of actual work :)

    I'm a lot more familiar with the tools now, though. The next one should be easier!

I remember you shared this video in the USACO Server. But once again, I'd like to say that this was a really amazing video!

    I'm glad you think it's of similar quality to the EDU videos haha. I think this particular video is for a slightly different audience, but maybe animations would be useful in teaching concepts on EDU as well!

Wow, that's insane. It's ASMR, for Codeforces.

This is very impressive--definitely one of the most educational CP videos I've seen in a while (not to mention high-effort!). The animation quality and design is superb, and you've done a great job making it rigorous and complete enough to be educational to high-level CPers while also intuitive enough to perhaps be accessible to a general audience.

I'd love to see more videos like this--one idea is that it might be helpful to make similar animations focused on algorithms in addition to specific problems. I think this style would be especially well-suited to explaining data structures (e.g. BIT, segtree, lazy propagation, etc), and perhaps it might also work well for graph algorithms, though there's more existing content related to those.

    Incredibly honored that you enjoyed it :)

    I totally agree that this style would be great for visualizing data structures. I'm thinking about doing a mix of specific-problem-narrative-type videos and more general educational ones.

    Thanks again for the feedback!

This is a wonderful idea! I believe videos of this kind, are the most crucial asset that our community lacks.

A good idea would be to make videos about classical problems, algorithms, data structures and other educational topics in competitive programming (like Shortest Paths, String Matching, Maximum Flow, Geometry, Segment Trees and so on). A good point would be to also touch other subjects from math and computer science. This way, you will make your videos truly popular, because many people are in search of graphical content that would help them improve in programming, math, cp and comp-sci.

Good job! And I hope to see your channel grow over 1 million subscribers, and to see it full of a ton of beautiful videos like this.

    Yeah, the plan is to do a mix of classical problems and random cool ones I find :)

[As a constructive feedback, the only thing I can find to mention is the occasional change in audio, e.g 0:46]

Well everyone has already mentioned how good the visualization and explanation is. I just wanted to point out that the editing is also very interesting. The music and the style of presenting builds a nice tension towards the final conclusion and solution of the problem. I really liked that. We need more these videos regarding algorithmic problems.

Really great video I love 3blue1brown, the guy is awesome. Watching your video was like I was watching one of his, really astounding work from your part. Congratulations!!!.

It is really amazing how the intuition of the algorithm comes alive with the animation. One last thing, good luck for the #SoME2 from the ones I have seen this year yours is one of the best (I haven't seen many tho only the ones related with coding).

2 minutes in, this is already super enjoyable. As an 'editor' myself, I see how much of work it is, appreciated & subbed instantly. I hope this one grows a lot!

Although, the only complain I have is to lower the BG music a little. It's a little louder than your voice sometimes, thus a little distracting.
