Stack is Last in, first out (LIFO). Queue is first in, first out (FIFO).

[@software-with-rosh]

This is really well done! I love the focus on concepts rather than just the “big-Oh” times. And the examples made it pretty clear on when they’re useful, so this was awesome!

[@PoojaDutt]

Thanks so much! I appreciate the kind words 😀

[@davemerkury]

Outstanding video @PoojaDutt!!!! By far, one of the best explanations of some of the common DSA's used in code on YT! Keep it up!!!

Thanks so much! I really appreciate that 😀

Awesome, wish I had a lecturer like you in my college. We just got a mini DSA pack in this, thanks for the video. It would be great we get a whole DSA Playlist from you 🙏

[@danser_theplayer01]

In javascript "arrays" are done with Typed Array magic class where you can only store numbers (they can be resizable). And Array is actually a resizable "struct" (? or buffer I guess) of pointers that point each to their data, so the data of the whole Array is sparsely stored in memory. You can also just make a binary ArrayBuffer and interpret it however you like.

[@Android-17]

A really great introduction to DSA, with examples. Thank you!

[@PoojaDutt]

No problem, glad it was helpful!!

[@saikrishna4026]

Why 0's and 1's means It represents +5 and -5 volt ... Its like giving power and stopping power to the conductor....so in that way a set of 0s and 1s represents plus and 0 ...0001 represents the bits

[@jovanaycart]

Love your videos! The animation and editing looks so good, and the content is so helpful.

[@anuragchakrabarty]

Man this is kind of lesson one needs truly, the principles of the data Structures were explained so clearly. Thank youu :)

[@tahmidamajumder5067]

I was finding it harder to understand DS until I came across your video. Thank you for using such amazing daily life example to visualize all the concept.

[@danser_theplayer01]

I'd like to note that "linked list" is kind of an umbrella term and nothing is stopping you from linking the nodes in it with 2 or 15 neighbours (though you might be running into graph or tree territory), creating vastly different performance considerations.

[@supremely450]

Great high level overview of most common ds. Nice for refreshing and understang at a basic level.

[@tukurhamid]

Thank you Pooja. You made it so simple that's readily absorbed! ❤

[@Artofnatiee]

Amazing video Pooja!! I was fascinated by your analogies and examples really improved my understanding of the data structures. I am definitely checking out your video on algorithms next. Cheers!

[@DineshGgoogle]

thanks learning for my day is from you. FYI : FIFO is mentioned as FEFO in the Queue chapter

[@shilpadutt5122]

You make it seem so easy - great video !

[@PoojaDutt]

Awww thank you!!

[@NaveenSingh-kx8uu]

that's a problem, right ?🤣

[@iakhileshsoni]

How beautifully and simply you've explained ☺ Amazing video Pooja👍

[@Ryan-qu4vx]

Very good video, in case it hasn't been mentioned the reason 0 index is the default is because it allow you to do modular arithmetic on the indices. If you've ever had the pain of trying to do modular arithmetic on a base 1 language, first I'm sorry, second you will understand exactly why 0 is the default.

[@alirezarezaei8624]

An ArrayList is actually an array and the size is fixed, but we don't handle the resizing or ... The collection interface is handling it.

[@vladimir0rus]

Under the hood, ArrayList uses an array. This means that removing and inserting items has a large overhead from shifting all the other items around. For that reason, we should look to avoid this method if possible.

[@Traveltheworldforfun]

It was really helpful and what a great way to explain.

[@BUNNY-qp2ds]

Which code editor are you using??

[@vladimir0rus]

The array starts with 0 is because the index is an offset inside the array. If you need to access the very first element your offset should be 0.

[@gopesh97]

Ther'es a reason why array indexing starts with 0, not a rule.

[@wixse.quisee]

Thats how I learned it. You gotta make real life examples of it. I used actual file folders to break down the different search algorithms

[@graziribeiros]

Wow loved this video! I made a career change to software development and I've a lot of stuff to learn, I'm working as a junior and I want to learn more about data structures and algorithms to get to the next level. This video is great introduction thanks❤

[@PoojaDutt]

So glad the video was helpful! 😀

[@priyankaprabakaran1235]

what editing software you are using for editing your videos?

[@julia_rodrigo]

This is such a creative video! xD thank you! I understand data structure more now

[@bhoot-eu1he]

I know why starting from 0 because it reduce one minus operation calculation each time when we finding index location of index find by base address and index*size of element but this index is come by relative index for find relative index we perform operations indexe - lower index, hear if lower index is 0 than we not need this - calculation because of this we start with 0

[@abdlhkam74]

Awesome explanations ! Thanks ! ❤❤

[@PoojaDutt]

No problem!!

[@God0f0dd]

So.. First In First Out -> FIFO Last In First Out -> LIFO They're acronyms. There's no LEFO/FEFO. It's just that when some people pronounce the acronyms as a word, they make the 'I' sound like 'ee' rather than 'eye' Also, I don't think many list implementations are using just singly linked lists these days. But I've also never written a line of Java, so I don't know. It's also important to note that a family tree isn't actually a very good analog of a computer science tree. Generally CS trees have the constraint that any given node only has one parent, otherwise you get the more general data structure, a graph. One more nit: a tree is not at all like a hashmap. Hash maps use a hashing function to determine a slot to store entries and then a secondary data structure to handle collisions. In fact, a hash map might end up being built of many trees! Trees are, rather, more general cases of lists in which a node can have any number of children, but may only have one parent.
