60% through the video but just can't hold in the comment any longer. this is by far the best big-O notation explanation I've ever encountered in my life. I have bachelor in computer science and master in AI systems, and have solved a bit more than 300 leetcode problems, aside from almost 8 years of software engineer production experience, yet nobody was able to explain this better to me than you did. an absolutely amazing visualisation! before this video I knew the most of basic notations (O(n), O(n^2) etc), yet I was still struggling with logarythmic ones. HUUUUUGE thank you for this. It's almost unbelievable the content of this quality is out here on youtube for free!

Time stamps in description very helpful - thanks! 1:48 - O(1) 2:55 - O(n) 6:35 - O(n^2) 9:30 - O(n * m) 10:02 - O(n^3) 10:45 - O(logn) 13:18 - O(nlogn) 14:58 - O(2^n) 17:30 - O(sqrt(n)) 18:26 - O(n!) 19:26 - Conclusion
@jspanchal
Possibly the simplest way of explaining Big-O notations. Kudos.
@Jaybearno
9:08 your simple, intuitive explanation on the proof of recursive loop is amazing. I took combinatorics classes in college where it took a professor 40 minutes to convey the similar intuition. To everyone out there feeling Fomo on college-- don't.
@terrypark3690
I've seen a ton of algorithm lectures and your videoes are the only ones that have finally gotten through to me thank you for making them!
@sriramannadurai9287
Man, the way you explain things keeps me locked in for some reason. Everything you explain goes straight into my head. ❤
@indianengineer5802
Thanks for being active on YT for the ones wo can't afford your course 🙂
@Caggen218
Been having some issues wrapping my head around parts of big-O, and this was precisely the explanation I needed for the last bits to snap into place! Cheers!

The "for coding interviews" was what lead me to click on this one over the other 10 "Big-O Notation" videos I had recommended to me
@dghj-x5z
I wasnt sure what Big O even is and I just learned how I can find it directly from random codes. THanks!
@ShamleThilaksiri
This video was by far the best video I have come across when studying about O notation. Thank you
@nischayagrawalVlogs
Bruh how do you explain things so well? Like seriously...not everyone who knows dsa has the potential to lay things out so easily. Your explanation has helped me a lot in many problems. Thanks a bunch man. Thanks a bunch.
@alonewithgodd
Took me a long time to comprehend this but I’m finally certain I completely understand how this works
@bubblebath2892
I feel blessed that you are on youtube and I found you as a teacher
@lorenainfanter.3099
This is the best explanatory video I've seen about Big-O notation. You make it friendly to understand. Thank you very much!
@carlossouza5151
This is the best explanation on YouTube about the topic, congrats
@yizhou2675
Love the way you explain things, so clear and creative and EASY to understand!!
@RafałNiemczyk-i7s
Wonderful explanation. I have bachelor degree of IT and only now have I understood what big notation is all about. Thank you
@samanthapennington4232
This is a brilliant - I am definitely showing this to my students to help them understand Big O notation.
