Great video Greg!
Maybe this playlist will turn into one of the best Python DSA course on youtube ;)

I've never though in my life that data structures is that interesting, thanks for the tutorial Greg

[Jafar]

Please continue adding more videos on data structures and algorithms (DSA) in Python; they are really helpful.

I was aware of your channel for quite some time, read and churned through numerous dsa and python da books. This content is golden and the best that I have seen on youtube to date. Keep up the great work Greg!

[blazenetic]

Wow. Huge thank you, best explanation yet. Your teaching abilities seem magical.

[ahnaftanjid]

your explanation is so soothing. Already watched DSA 1-6. Please bring more.

Really loved how well scaffolded and structure this video is! Knew about big O but your video was definitely one of the best explanations I've come across 🎉 with simple to understand functions before delving into the concepts mathematically. Thanks for the great work done

Babe new video dropped from Greg Hogg new DSA series..

[aaronlobo]

Thanks alot bro!
Your videos are amazing.. Please keep teaching DSA!

[ParthMakwana-dzyh]

Can you please tell me which whiteboard you are using?

[jamestacular]

I’m confused. Isn’t the second example O(n*logn) since you’re not traversing through the entire array for each number? Just the remaining possibilities of unique numbers? With n^2 you’d get 25 possibilities but here you get 15

[muniswamivikram]

Yes I also waiting for machine learning

[KingJon]

Thanks for this definitely going to check it out. Would you recommend using this over the San Diego dsa course on coursera?

[Andrew_N_G]

Hey bro have you covered strings i am not able to find the lecture

[juhi_rathor]

have you made notes for whatever you are covering up in the videos?

[I_world]

Hi I’m a beginner at DSA, should I watch all the tutorials before jump to the leetcode?
