This has to be one of the best, most thorough, beginner friendly, and most simple ways of explaining this subject. Most other tutorials brush past that clear explanation you delivered with the initial graph and end up losing their audience in a swamp of technical jargon overload to the point where they give up. Thank you for your clarity on this important topic!

I'm a self taught developer getting ready for technical interviews. This video is the best one on YouTube covering big O notation

I could cry, thank you so much. This is the first time Big 0 has ever made sense to me. I cannot thank you enough, you're an excellent teacher. Thank you for starting with the benefits of Big O (the why we need it) before jumping into to the hows. I'm always a why person and most folks just jump into teaching you how to find it. The visual graph in the beginning for someone whose background is not in math was extremely helpful.

This is by far the best explanation I've seen/read/heard.

The best explanation of Big O I've found so far :) Thanks

This is the best video to start with if you wanna know about Big O notation from zero knowledge of it. Thanks Steele

If you know nothing about time complexity .. this is the perfect video ... explained in the most easiest way possible ...

[falconiere]

This is the best explanation I've seen in my life about Big O notation. You are the best!

I've graduated with a computer science degree and never really understood Big O until now. Thank you so much. It was always so confusing from my professors

[Shad]

thats why he's the best..takes complex topic and makes it seem so simple...God bless you Colt

[robinwarden]

This video has helped me much!!! No one else could clearly explain to me what Big O actually was. You've officially succeeded in translating the Japanese.

BEST explanation of Big O I've found. Thank you SO much! --From someone who didn't take decent math in school

[landrybenimana]

I read a comment that this is the best video on big o notation, now I agree. He was simple and to the point perfect for noobies or even intermediates. Thanx Colt. I'd love to see more videos on different topics of programming and competitive programming.

WONDERFUL video!! I’m a beginner coding student and this video was THE MOST helpful and easy to follow and understand video I’ve found. Well spoke and very clear. You explained everything in simple terms with wonderful graphics. Thank you!!!

[arteria]

Thank you so much! Finally! Someone who can make this topic seem easy to understand.

[robertsiepkowski]

I watch dozens of different teachers on many different platforms and you are the only one who seems to keep me engaged. I can't pinpoint what makes you so much better, but I just learn from you and I actually finish your videos and understand what the heck you're saying. You truly have a gift Colt. We are very lucky you decided to become a teacher. Thank you for all that you do.

This is one of the most intimidating CPSC subjects in our engineering program. I was also asked questions about this in a firmware validation job interview. I really wish you had covered this when I was taking that CPSC course. You are a year late! 🤣 thanks for the great content and your top notch courses on Udemy.

Seriously, one of the best tutorials on Big O notation. Really liked it a lot!
