Very clumsy explanation

I feel the udemy
https://www.udemy.com/course/the-bible-of-algorithms-and-interview-questions/
course is way cleaner and easy to understand then explanations here . No intutive logical thinking process is shown.
I am not able to understand the very first video as well that properly. Please do help

Do you have doubt in the bitonic subsequence problem?

I understood it in the second try of watching the video. And the white board is deleted and again writing it makes it clumsy. to keep track of the thought process.

And so many circles and scratches and rough lines makes it unclear sometimes

Yeah I agree explanation got a bit messy, but this was probably one of those times. If you watch the videos with a pen and paper, you should be able to grasp the concepts. This course has benefited hundreds of students, so you can trust this content to make you a better problem solver by the end of its duration.

I hope I’ve cleared your doubt. I ask you to please rate your experience here
