Time Complexity and Big O Notation - Data Structures and Algorithms

Isn't O(n^2) is slower than O(2n). Not to point out a mistake but letting know everyone not just copy paste.

Thank You!

you must include a class on Array as well as common mathematics like n! log and etc

The best explanation of big O notation I've ever watched, thank you.

Every one just use the graph and tell you this is o(n) this is o(1) this is o (log n) but noone explains the math behind it.

so do we jsut memorize this and when we are ask just blur out what we think we know.

man you are the best.

Is the hash key unique in every list? How does it sort and search for hash keys?

had a question: For O(n), will it still be linear if n was like 9 but it found the number it wants in an array at index 2 or something? because wouldnt that be 3 operations, making it not linear? love your video!

thank you
Clear explanation😇😇😇😇😇😇😇

Thank you, this is make my day!

These are a good damn videos, I don't know why the heck is not more visited. By the way, for all of us college students of CS, we appreciate these kind of videos. Thank you Caleb.

junk like that ..

You are so much better than my uni professor!!!! I get it now! You're so cute too :)

Thank you man. You explained this concept so simplistically for me

Sir what is your name

thanks for the video

Caleb said he stinks at math in this video. A few weeks ago I needed to learn binary counting and this man was able to teach me how to do just that via a video he made when he was a young kid.

Thank you so much!! You have a great explanation skill bro! Keep teaching us👍🏻👍🏻👍🏻

Clear explanations

Clear explanations: ✔️
Useful analogies: ✔️
Not monotone: ✔️
Confident: ✔️

You're a different breed, Caleb. Amazing teacher

This guy is awesome! :D

Wow It's great video from caleb

the n! slowmo cracked me up

thanks a lot

Crypto buddy ! Amazing teach.

thx a lot!

Thanks Caleb.

This is the best explaination I have seen about bigO. "number of operations", this enlighten me, make it is easier to understand an abstract theory like BigO. Thank you very much.

Before watching this video I'd read all this stuff and didn't understand a thing. Now not only I understand, but even like it)) Thanks a lot!

Hey Caleb Curry, where do I access the code for this video?

thanks for this vid 🙏🏾🙏🏾

I'm studying for my data structures test rn. Wish me luck ;P Thanks for the great content!

Astounding !

Wow thanks

That's the ugliest drawing of a car I've ever seen XD. But anyway, great video!

This video deserves millions of views!

Very cool

I appreciate you. Thank you.

Dude you are so cool, I've watched many of your tutorials and they all ROCK!

when the lecture ends and I hear the music it fells like I'm in a different world.

I swear you Summed up an hour of my professor's explanation time much better and I actually understand, THANK YOU

Thank you Caleb this was the best tutorial to help me understand these concepts

Watched the freeCodeCamp 8 hour video on data structures start to finish. Nothing made sense until I started watching this series.

I really liked the parallel with a car. This is for sure the best explanation of BigO on whole internet :)

This guy makes difficult concepts look easy by his ability to simplify things. Thanks a million
