Hello everybody!

It's been a while since I last posted a video tutorial, and since the previous one received a really positive feedback, I decided to create another tutorial. Since it's generally a data structure which isn't that loved by many competitive programmers, and it has also been suggested by many people in my Discord server, I decided to create a detailed video tutorial about Fenwick Trees.

I explained everything about Fenwick Trees, starting from basics and going all the way to the less well known optimizations, as well as explaining when Fenwick Trees are useful and why should they get more love from the community.

Here is the video

As always, if you have constructive feedback, please share it in comments or in the Discord server.

Thank you for watching.
