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

[@robertsiepkowski6479]

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.

[@petercannon1865]

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!

[@ColtSteeleCode]

Thanks, Peter! Big O is tough to teach, but that's what makes it fun to me. I think the topic itself isn't all that exciting, but it's fun to try and come up with ways to explain such a dense/technical thing.

[@DanT-iu6oc]

this completely explains hacker rank's shitty explanation. that woman is an absolute idiot explaining nonsense

[@rodanm]

@@DanT-iu6oc Bro, dont be a pussy nor hater.. Colt, sorry for making fight here, just defending humanity and education.

[@majia]

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.

[@Abhi-oo9ki]

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

[@masoudmokhtari3904]

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.

[@dandandan01]

This is the best video and explanation of Big O that I've seen and I feel like this should be shown in all CS courses. Thank you so much for this, you've helped me a ton and got yourself another subscriber.

[@landrybenimana7183]

This is the best explanation video I've run across so far, super simple and to the point

[@jacsonmiranda]

searching for this subject on youtube, than I recognized Colt's voice (I took bootcamp course). Good lessons as always

[@saurabhjethi3859]

So far the best explanation! Have been going through several videos to understand and with the details and examples in this one, this makes it easy to understand! Thank you for this!

[@AF-bn3ps]

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!!!

[@robinwarden3864]

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

[@Engbic]

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

[@andriitynok3897]

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

Best video on KZbin about the subject. Well done!

[@adityaojha5776]

[@zizothegreat2769]

I am currently taking your MySQL class on Udemy. I surprisingly stumbled on this video and was like waiiiit a minute, I know that voice lol

[@pilatec]

The Big O notation concept felt abstract and complicated to me until i came across Colt's explanation. I'm like, "how could i have not understood this!". Thank you so so so much man!

[@arteria6536]

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

[@narasimharao7007]

i have searched for too many videos for BIG O, but after seeing this i got answer for BIG O thanks a lot bro

[@Ravetoon]

Great explanation and breakdown of the examples. I definitely have a better grasp of Big O Notation now.

[@tomascanevaro4292]

Helped me a lot to understand my algorithms course in collage. Thank you so much!

[@hyrdeshgangwar]

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

[@ejiroolokpa4933]

Thank you ! I have watched many other videos, and this video gave me a better understanding of the Big O Notation. Keep up the good work :)

[@RyanTosh]

The cats staring into my soul while you talked about subscribing definitely worked...cats are the best strategy.

[@ddaanniieellllee]

New to programming and I’m trying to get down the key concepts and big o notation has always been confusing but this is the best explanation I’ve stumbled upon yet! Also noticed on the description you have a springboard boot camp, I’ve been hesitant about dropping bucks on boot camps but I would totally take that if you are still teaching it

[@armsjarbc8597]

Your a really good teacher, I’m glad I found this video

[@chorton53]

I found your video very clear and easy to understand. Thanks and Happy Holidays !

[@Fer-jf3pl]

Wow best Big O explanation on KZbin. Thanks!

[@jstn7659]

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

[@ekings2119]

Thank you so much. The little exercises at the end are surprisingly helpful.

[@thedbzr213]

Dude! oh my goodness that totally helped it “click”! Thanks for the video it was short but very clear and understandable. Totally getting a sub from me thanks again!
