[@mehdisanjaghi292]

do you have an algorithm to unmerge/split a tree?

[@mackenziejackson2888]

I can't show enough appreciation for you diving into data structures. I am preparing to go into a data structures course this fall and you have been invaluable in introducing these concepts. Not only do I feel less intimated but you have a way of making these videos interesting and fun. Many of my classmates feel the same way. Your teaching reminds me why I wanted to study programming in the first place.

[@phantomghoul2846]

i can't believe this is better than the damn courses I bought on skillshare. straight right to the point and showing us the common functions that are going to be used. kudos and thanks for this video

[@user-us1un9rm8r]

I come straight to your page for every new week of content in my C++ class. Thank you!

[@bl00dspec75]

Hey Saldina. I first saw you on the freeCodeCamp video and immediately connected with your teaching style. I have been loving the data structures series so far. Both the C++ video and this series helped a great extent in coming back to C++ after about 6 years. I feel like if you could continue the data structures series it would have been great - implementing different styles and algorithms in the way. These can be concepts like recursion, backtracking, two pointer approach, sliding window, dynamic programming. You get the gist :D Anyway, thanks for all this. Greatly appreciate it!

[@igor-haha]

Odlični videi Saldina! Jako lepo objašnjavaš, jednostavno a ipak kažeš sve bitno, i još pokažeš na primerima. Hvala na trudu, samo tako nastavi! Pozdrav iz Srbije

[@yangamasibulelemdede4191]

I really enjoyed your video, I am a University student (South Africa) doing Computer Science second year this year... and I really admire your tutorials. This is surely a channel I will recommend to all IT and Computer Science students. I remember last year when I was a first-year student; so in the first semester I did Problem Solving in C++ and because by then I didn't know you yet, I got 54% as my final grade for Problem Solving (that's bad). And in the second semester, we did OOP in C++, and I was really struggling with it. But after bumping in your videos my marks went skyrocketing up, and I got 73% in OOP as my final mark, could you imagine, I knew you (your KZbin videos) just two weeks before writing the final OOP exam but I managed to get a better grade. This year I am getting abused by C++ Data Structures, it's hard but I'm giving it my all, and lucky enough I have you at my rescue. @CodeBeauty You are the best.🤝👏👏

[@CodeBeauty]

I appreciate this so much 💓

[@gammyhorse]

This channel is a precious gem.

[@mr.potato8894]

The timing of this video is perfect. Just started learning this in university. Now I can learn ahead and show off next class xD

[@CodeBeauty]

Some people are striving to be the best. Way to go!! ✨✨

[@jovanaycart]

Your videos are the most helpful on data structure foundations and c++ that I’ve found on all of KZbin. Thank you! Could you do a video of black red trees

[@crazyzombie9720]

I’m currently in a Data Structures class at my university. When we got to trees, that’s when this video was uploaded 🤯

[@CodeBeauty]

it's a sign 😃😃

[@AdrianPerez-mr1nd]

I’m also enrolled in data structures at my local university. This is very helpful!

[@TonyStark-lw7lv]

Thanks for starting this topic. Waited for this 🤝🏻. Thank You Again.

[@Rebel084]

Yo I’m literally working on a project in class for this!!! Perfect timing

[@PreludeSon]

This is such a great tutorial...the pictorial truly help.

[@mariacunha8508]

I really appreciate this videos!!! Thank you so so much!

[@Reem-du7sd]

YESS! Another video! Hope you can upload a part 2 to the doubly linked list as well. :) Keep up the great work! You're saving every c++ beginner at a time ❤

[@granumuse7847]

First of all, your narrating "bugs" are not that bad as you think 🤣 This intensity of them is created only in your brain, as a result of the conflict between what you expected and what finally occurred 😊 To us, nothing bad happened at all. Secondly, bravo!!! The easiest explanation of tree data structure on KZbin. Thank you 💖

[@nguyenviet908]

thank you very much, wishing you all the best!

[@luisalamo2658]

You're terrific at explaining these concepts in such a simple manner. Thanks a lot, I can remember at university a few years ago when I was afraid about this tree data structure.

[@birger928]

Thank you! You are great! 👏🏼

[@techymoh]

Just going through DSA and this is helpful.

[@leoleo20100216]

Very clear explanation for binary tree c++ implementation

[@tobiluchi911]

Wowww that's what I'll be learning this year! Thanks a lot ;))

[@dongyangchen5460]

they are very helpful, ty!

[@MarcusHCrawford]

Your videos are so helpful. Thank you!

[@CodeBeauty]

I'm glad to hear that! 🥰

[@G_.G_.G]

Really thankyou for this video This video clear my doubt which I have been searching for few hours.

[@BantuBeast]

Thank you!

[@ngongocnam4239]

I love you. My teacher ❤. You was explained clearly and easy to understand what things you wanna share to others

[@peterchisangamwamba9100]

thanks patiently waiting for the next video on trees

[@railway-trainstramssubways1584]

Greetings from nearby Bulgaria! Great video! Currently studying c++ programming in the university and your videos help a lot!

[@mahmoudhagag4234]

Welcome back, we missed you💙

[@nagen78]

your tutorials are superb and looking forward for similar tutorials in Python

[@temirkhanamanbaev42]

You are great 👍!

[@abdelmalek9004]

if the children are connected it would be a graph data structure instead of tree

[@CodeBeauty]

Yess 😁

[@rmt3589]

Thank you so much! It's what I'm actually looking for!

[@MarcusHCrawford]

All trees are graphs.

[@davronxonmuxamedaliyev4377]

You are indeed, the teacher every student dreams of...😂

[@AwaisKhan-th8fo]

Thanks you so much ma'am.

[@Edxylom]

I love Saldina I was need this video! a Video explain Hash Tables will be amazin!!

[@emmanuelsharp7031]

you are a blessing

[@DRdr123]

Thank you 😊 from Egypt

[@leoara8019]

great video in perfect time...thank you so much for the video.

[@suhas5605]

Please complete data structures as soon as possible with all topics covered...

[@asthajain7207]

Now I started understanding things better by your video could you please upload a video on a circular linked list...... ♥️♥️

[@SavageScientist]

Awesome video great content

[@faujayikhsan2194]

appreciate, thank you so much for this, hope you have a wonderful day

[@HeyitsGift]

THANK YOU FOR THIS!! I have literally been checking weekly for a new video by you 🥺❤ & you came through!

[@CodeBeauty]

❤️❤️

[@sikirusalau9460]

This is awesome! Thanks for explaining in a easy to understand way. How do you free the memory created by the new keyword? I understand delete is used to free memory or sometimes calling a destructor but I'll like to know how you free the memory.

[@dedsec2084]

Hi can you make series on python your concepts are so easy to understand and it would be awesome you make a series on this language btw love your videos

[@mindlessmeat4055]

Coming from a mathematics background, trees are something i have studied in various classes. Thank you for your videos, they are immensely helpful. Does the data have to be integers or can they be some other type of sequential reference system? Like what if it was a list of college classes? They are list like math101 or cs101.

[@UnrealCatDev]

Very gut video

[@tryit1568]

Thanks so much for this !!!! I love these Data Structure Videos Graph Data structures next please 🙏!! ❤️❤️

[@dileep.b5054]

please make a video on UML DIAGRAMS as soon as possible

[@saifmos6516]

i would really love to know your settings on vs , wuth that i mean for example your code formats , could you please share this with us ? thank you : )

[@ladymorwendaebrethil-feani4031]

Perfect.

[@BunnyHuggerr]

First of all thanks for your amazing tutorials! helped me a lot with C++ OOP. Off topic - are you going to teach as well C#?

[@CodeBeauty]

I might do a C# course as well. I love C# and I've been working in it for 5+ years, so if there is enough interest I would gladly do that course :D

[@BunnyHuggerr]

@@CodeBeauty Amazing :D just started programming less then 2 years ago and no idea why I found it a bit harder then I thought it would be. :| Thanks again for your time and afford! most appreciated !

[@noobclasher7471]

Badly need it...your videos saved my exam last week....this topic coverd in recent class but i don’t understand well..thanks and take ❤️❤️❤️❤️

[@CodeBeauty]

Even though I finished University a long time ago, I still remember the feeling of trying to focus and follow the lectures, but not understanding ANYTHING! That's why I make detailed and step-by-step lessons and cover all the important facts, so that it is easy to learn and make progress. 🥰

[@nasiriqbal6004]

Love you from Pakistan. You speaking and teaching style is behind the boundaries

[@nasiriqbal6004]

@codebeauty Please Cover the Whole Tree. i think you can teach us better than any programmer.

[@chiragsawajiyani8540]

Can you please make a full detail course for c#.

[@mehdisanjaghi292]

do you have an algorithm to unmerge/split a tree?

[@voidray0988]

Can you please make a video about how to take a line from a file and put it in a fuction ...and i love your videos you help a lot of people keep it up😁😁

[@julioventura2867]

a little question , i 've been asked to do a binary search tree data structure, but there are values that are the same as others, how do you deal with that ?

[@johnnycanuck6923]

Hey Saldina, thanks for your information! If you were my teacher when younger I would be better than Billy Gates now LOL!!

[@Sportsman134]

for the BST rule described at 8:50 (left child should have the value smaller than its parent, right child should have the value larger than its parent), does that mean if you input the following values in this order: 30, 15, 20, 40, 50, 55 (without giving it left,right ordering), it would have to populate a tree the same as in your example?

[@mudkiptheengineer5339]

The BST tree is also known as red black tree, in order for it to work the data type can be compared, in this case you are talking about ints so it would be done automatically, but if it were a user defined type you'd have to overload the '>' operator

[@aliomidi9613]

your teach better than my university professor

[@anschoudhary1376]

for 12:07 can we do newNode->left && newNode->right = nullptr;

[@ajitpatil6532]

Just about 3 days ago I was trying to find your video for this topic, and today you posted it!

[@remimonsel9944]

Hello, I watched the liked lists videos you created and in there when creating a Node, you created a class and here it's a struct for the node. Is there a reason why not using class as well here ? or we can use one or the other it doesn't matter ?

[@Asterics.]

thank you bst 😉

[@CodeBeauty]

Welcome 😊

[@kamilaarshad5427]

why we are using Node * as data type for left and right node

[@jasonyu7963]

if the child are also connected is it a circular singly linked list?

[@adilkayani]

This lady is a codebeauty and a real beauty. )) And funny too. )) I mean, she has a great sense of humor.

[@Tech_Diaries_With_Vincent]

amazing😍

[@CodeBeauty]

I'm happy to hear that 🥰

[@tarekbenlakri1058]

hey could you answering me what is the difference between NULL and nullptr

[@pikimk6167]

Graph, and i hope you make a video about graphs 😀

[@CodeBeauty]

Yes, correct answer 😃😃

[@montyGator]

I don't quite understand line thirteen in the createNode function, can anyone explain that to me?

[@spicyshizz2850]

Bsts trees bruh ;)

[@aliniaz6448]

If you open cmd in a specific folder and type tree command cmd will show you the tree of that folder

[@CodeBeauty]

Yes, great example! 💜💜

[@MrLaruzer987]

How do I identifier not found On root = createNode(1);

[@ChandanDas-kz5wq]

Is that structure "doubly circular linked list"?

[@gauravpathak560]

hii selena ur way to teach is really awesome. U make more videos on DS and Algorithms . Kindly cover trees and graph important algos also.Keep it up....

[@robertpaukovic6811]

nullprt was not declared in the scope ??

[@chrishabgood8900]

It’s like double link list?

[@jameskaiser7474]

What do a root node and batman have in common?

[@JorielTejada-te4dd]

How about Graph Data Structure? Can You teach us about that algorithm? please?

[@thealphabetissilent3447]

What is the DSt at 6:10?

[@orangeeezoe]

Is that the graph data structure for the closed loop?

[@_Omni]

Yes

[@nanof1948]

can you make video's to explain java

[@ehapahmed1069]

will it differ if I used class instead of struct ?

[@CodeBeauty]

Nope, but there is one important difference between class and structure. Do you know what it is? 😃

[@simplyritik]

Bssst🐝

[@Thebiggame-dc8ek]

I paused the video and now I want to answer your question😁. we can create a left node with the createNode function, for example, and give its address to the pointer of the root.

[@CodeBeauty]

Did you continue watching the video, is your answer correct? 😃👊👍

[@linhtetaung2613]

directed acyclic graph

[@mayabouban379]

cyclic graph can be represented by a doubly linked list

[@mayabouban379]

Now I'm a 3rd year student in cs and in my first and second year you helped me a lot I'm very thankful for your help after watching your 10 hours tutorial I get 93/100 in my first exam in c++ Thank you so much

[@mudkiptheengineer5339]

if I'm not mistaken, the "BST" tree is also called a RedBlack tree

[@adreezy6576]

Referred a binary search tree as a BSSTTTT to my professor and he almost had a heart attack

[@infamoustony]

the data structure on 3:35 is graph

[@CodeBeauty]

Yes 👍🤗

[@hisoka7489]

So.... what is the data structure in the min 3:46?

[@richardshane2080]

Theoretically the Earth's population that's plugged in is a bit less than the total population, however the theoretical limit with a database is the hardware lol ....lovee de program on anything especially binary......ty, big hugs 🤗 everyone

[@arshmaanali714]

Thank you so 😍😍much mam ❤️🇵🇰🇵🇰🇵🇰

[@namelessboy55699]

an intelligent and beautiful woman indeed, cant get tired of watching your tutorial and you

[@Matice21]

I don’t understand newNode->left = newNode ->right = nullptr. Is this just setting both the left & right to null? Is it the same as newNode->left = nullptr newNode->right = nullptr // ?

[@user-vi5ep1ox3z]

Your natural beauty truly shines when you're not wearing eyeglasses.

[@CodeBeauty]

I've spent many nights coding, so I get that's where my bad eyesight comes from. Thank you 🥰 ❤️
