As a current JAVA software developer, I have not been using more than 10% of my thinking power, and I can guarantee you don't need to fully understand the shxt in this video to do coding. Since most people NEVER understand business logic/idea, and they don't even understand their own code. They just copy existing code, edit it, turn them to trash code that somehow pass QA testing and code review, and thus, the trash code is in production.
@@caojidan8913 maybe that is true in your environment but unfortunately that is not how you pass interview for a developer especially junior they expect you to know a lot for data structure and algorithms you do not need to know perfectly how they work in reality but theoretically with examples for sure it is mandatory.
@Jerry Grauert Can you explain how it's constant time to insert element into LinkedList because if I want to insert an element at middle of list then I would have to iterate over first n/2 elements right? So it would be O(n)
No, all you do it ‘disconnect’ the pointer between the two nodes you are inserting. Then you point the previous node to the inserted node, and point the inserted node to the next node. Insertions is always O(1).
Your videos on programming are some of the absolute best I’ve ever seen. Keep it up, I’ve referred so many noobs to these lately. Great paced explanations and visual aids. Top notch, really.
They don't necessarily explain it better, but because your professors have already introduced you to the topic, it becomes way easier to digest the second time you encounter it through youtube.
Because universities usually aim to educate for research and academical careeers. Not nescessarly to match market demands of programmers. And professors are usually very academically merited but that won't guarantee a pedagogical skill. And youtubers are very pragmatic, explaining a specific topic in a specific context usually. And not always right either - in the sense that they tend to simplify or focus only on parts of interest. Neither is bad, but it's a little like comparing apples and pears, or something. Aaron does a very good job in opening up the world of getting software jobs "in the industry", at least from his poinr of view. And he's very good at explaining too. That's for sure.
One video, and I'm subbed. I appreciate the high-level explanation of these DS's, as I am a student. Also, I dig the subtleties and nuance of your design/imagery in your videos. Strong work, please keep it going!
Your Awesome, I have a Master now working on my Ph.D. in DBA/Data Analytics with Certs in 8 Programming languages with repositories on GitHub BUT, I'm still not confident in this area of Data Structures/Algorithms. You have a new fan because I love your "Lay-Men" method of teaching.
Very well done. The clarity was on point and the examples were handled very well with just enough information for comprehension. Also, very good use of graphics to increase comprehension. Thanks!
Thanks for sharing your knowledge!! I really appreciate your teaching style! I process info differently than most... so, the visual aspects & examples really help make this info easier to grasp! Thanks!!👏🏼🎉🧡😁
i saw this video a few months back and didn't understand anything except arrays and objects. now that i studies all these basic data structures i can appreciate you simple/straight to the point presentation. Thank you so much
Aaron jack, I swear watching this video from you has made me more passionate in Computer Science than any of my profs have (aside from a few), but even then you motivated me more
Really great job! Quick and too the point! Would have been cool to have the big O notation for operations since you brought it up at the beginning, but maybe that is for another advanced video since this was aimed at not using as much jargon.
I’ve done a little bit of most types of tech jobs (web programming, DevOps, Data Eng) and I’ve always been intimidated by these concepts. I’m faced with having to find a new job and it’s been a bit terrifying having to get out there again. I am enormously grateful that I ran across this channel. I wish all teachers were as talented as you are at delivering information. You’ve given me hope.

You are the best programming teacher I’ve ever seen. I LOVE how you state the pros and cons and reasoning behind things. Thank you so much!!
Answer:
1) Linked lists,
2) Arrays,
3) Hash tables,
4) Stacks and queues,
5) Graphs and trees
But, what is the question?
thescales18 Is this Jeopardy? **What Are** “DATA STRUCTURES you MUST know”

@@flow5718 No worries.... the people who conceived Python and JS were obviously shy of any formal education as well.
Short, no BS. That's why I love you and I'm here. Thanks Aaron!
The editing really stood out in this video, great work!

Why do TH-cam guys explain concepts so much better than university professors?
they were at the same point as we are now
University professors don't have to be good teachers to be professors. TH-camrs need to be really good and entertaining to get enough viewers.
They know what they are talking about ;) :D

Aaron, your presentation and production had both really improved. Fantastic content.
Keep it up!
Your channel is a gem, i'm so glad that i've found It.
i love the darkness, feels like a true programmer
Dunno about that, I was kinda waiting for him to pull out a bong at the end.
and no plant or guitar in the background... or even (oh my gosh) a black cat😐
Dude. Never stop making your videos. You are clear, concise, to the point and you have clear thought processes.
Good work, subscribed. Thanks!

That was very fine explanation. Thank you!!
Excelent summary buddy. I loved it.
Great video! Can you possibly do a video showing examples of when to use each one of this algorithms in real life software engineering?
well explained + great examples
keep up your great work :)
Really great job! Quick and too the point! Would have been cool to have the big O notation for operations since you brought it up at the beginning, but maybe that is for another advanced video since this was aimed at not using as much jargon.
Love these short videos!
You did amazing works which transferring the boring things into vivid logical points.
I pause in the middle of the video to say how great your video is. It is fantastic. The way you putting things simply and obvious examples are great
