I'm planning to start a video series on my channel where I pick any problem and brainstorm the ideas (not the code or implementation details). Let me know if you like the format, if there's good traction, I'll continue the series. Feedback/suggestions welcomed.
The first video in the series is out, and it deals with how to start thinking on problems that involve lexicographical ordering of arrays.
Here is the video link https://youtu.be/QSEQvt5s7Zs
Thankyou for all the content you have offered till now. I want that, you continue with the type of video tutorials you create (not any new format).
Please take a look at this question: 2180E - XOR без эффекта. If you find it useful and concepts rich, please try making a video for this.
