[@graymatter1426]

Your video lessons are so helpful for my coding journey. The things which are hard to understand in textbook is easy to follow on your tutorial. Thanks for your amazing work ❤️

[@dundyd3612]

Amazing video! I can't explain how long I've been looing for a good explanation, glad I finally found it.

[@I_am_FRANCO]

Thanks mrs. puff for the vid

[@md.abubakkarsiddiq1156]

4,9,5,2,6,15,7,3,1 is the post order traversal. Is this the correct answer, please let me know.

[@emmanuelnsiah8036]

yes this is right

[@МаксСивухо]

Hello. It is the best explanation I've ever seen. Thank you for your lessons

[@CodeBeauty]

I'm glad to hear that and happy to help 😃😃

[@khusanumarov5834]

Cool! Very simple explaining. Thank you so much!!!

[@farbolos3164]

My placement session is coming, can you make more such videos on Data structures and algorithms, your explanations are very good🔥❤️

[@javiercantoy7522]

You explain very well 😉

[@peterchisangamwamba9100]

since you're learning algorithms like the video it helps youtube algorithms CLASSIC!!

[@jliu7221]

Better explained than those tedious and never-ending college CS courses. I enjoy your instructions. Simply Amazing!

[@azixkhan6632]

//Postorder algorithm (L,R,D) printTree(root->left); printTree(root->right); cout data

[@johnniewalkerjohnniewalker2459]

very comprehensive video Saldina.Your english also are awesome.Can you make if you find free time more video about windows forms applications?

[@Daniel-um9ye]

You managed to make this look super easy. The best traversing trees tutorial I have seen ( and I have seen a lot of them ).

[@dangerbirb4981]

This is the clearest explanation of DFS algorithms that I've seen. Thank you for making it easy (where my book and lecturer did not)!

[@montyGator]

Omg! I have never understood how a recursive function works until I watched this video! Your explanations are top notch!

[@charleswayne5581]

This is the most excellent explanation on recursion I have ever seen!

[@CodeBeauty]

I'm glad that you like it 🤗 🥰

[@adammed8667]

Very refreshing video... keep the good work up.

[@deli5777]

Maybe the most helpful video on recursion that I've seen

[@潘建廷-g3o]

Excellent video!! Could you update more algorithm-related Videos in the future? Your explanation is simple and good to understand.

[@howabadworld]

nice video!

[@CodeBeauty]

Thanks 🥰

[@МаксимУдовиченко-и1м]

Hello, Saldina! I am a Russian developer. Your videos are amazing! You explain the topic very clearly, giving examples from life! Looking forward to your new videos!

[@I_am_FRANCO]

Я люблю Россию

[@munib2023]

Upload all your STL videos in a single video as you did in C++. This will helped us alot.

[@Pirzade]

I want to add something. There are 6 possibilities for Depth First Search Algorithm according to the starting point in data structure. D refers to the Data, L refers to the Left, R refers to the Right pointer. The possibilities are; A-PreOrder (1-DLR, 2-DRL), B-InOrder (3-LDR, 4-RDL), C-PostOrder (5-LRD, 6-RLD)

[@noahgoss5552]

Hi Saldina! Amazing video :D I was wondering if in the future if you give a tutorial on vectors in C++? Most of the tutorials I looked up are a bit confusing and I feel like you can give some o fun clarity on this topic like you do with your other videos.

[@Pirzade]

One word is enough : Incredible.

[@Tech_Diaries_With_Vincent]

Thank you for this video, you made this topic and concept more understandable 😍

[@CodeBeauty]

You're welcome 😊 🥰

[@HiMiss940]

Your English is really good , i mean really easy to understand, good Word Choice ❤❤😊

Great explanation. God bless you 🙏

[@itsme17717]

you are awesome, I really understand trees right now

[@danonuevo]

Hello, thank you so much, and it's a very concise explanation for the DFS. May we request how about doing BFS with the same Tree example. More tutorial videos to come.

[@vincent_muriithi]

amazing, kindly create a BFS traversal algorithm video 😍

[@willofirony]

Explaining recursive functions is challenging and often confusing to the neophyte. Nevertheless, you tackled the challenge faultlessly. One wonders if, when searching, the algorithms would be more efficient if one compared the 'target' with the data and choosing the appropriate algorithm on the result. Are there generic algorithms for balancing the tree, should one side of a node gets much 'heavier' than the other?

[@Zita098765]

Thank you so much! Please please make a video of BFS!

[@alaeddinebenider205]

your video are so helpful

[@TheDima23]

Amazing video, thank you so much for this !

[@ookhands3843]

Hi, thanks for your explanation. I have questions about types of Trees and how they are used. Black-Red Tree for example. Or in which case we use DFS ? Thanks.

[@filipetaveiros6967]

Excellent explanation!

[@putin_navsegda6487]

Wow great explanation ! Finally i understand it😁

[@mihnea-um5gy]

Will you do a video for BST?

[@mr.potato8894]

Is it possible to get a virtual autograph? 😂😂

[@dundyd3612]

Hahahha, I was wondering the same :D

[@CodeBeauty]

Hahaha, something like my digital signature 😁 Maybe I'll make a few NFTs in the future and share them with my most active viewers 🤔😃

[@Mzkysti]

@@CodeBeauty this video is definitely worth of a coffee at least, I'll check how that works...

[@Marzex1x]

Thank you!

[@sononsoft5253]

The hardest thing about coding is not seeing what it does in the background. Your explanation is amazing and this is what people hope to see, especially me. Thank you so much!

[@tofiq62]

Very good explanation! 👏

[@Happys_Art]

Hello. Is it okay to use this code for my homework assignment for my class. To be honest I’ve ready used it for my assignment so technically I’m just informing you that I already used this code and wanted to ask if it was okay

[@nika_nothingmore]

your videos are amazing!

[@shinoke9395]

can you setup tour also i kinda waana know and thanks for the hard work....

[@Shinji91]

This helps so much. Thank you!

[@madhusankawijerathne8435]

Really helpful. Thank you!

[@alexanderlord1512]

Thank you for this vedio but i wish you make vedios about solve problems using dfs I couldn't solve any problem until now using it

[@sononsoft5253]

Do you have the video for BFS?

[@MuhammadBilal-j9x]

Hi i am trying to find how to deletion form Tree

[@bishoyzakhary3531]

amazing video I finally understand DFS ❤ ; can I ask you to make a video explaining BFS and red and black tree thank you

[@omerhusen906]

can you make more such videos on Data structures and algorithms? your explanations are very nice,and you are so beautyfull hhhh. thanks for you.

[@madhusankawijerathne8435]

Thank you again

[@انامسلموكفى]

I ve a struct of student with some properties : code is the identifier of the student, it will be the node in the binary search tree , first i would like to create a linked list of int from this struct ?? And then convert this linked list to a bst in a dynamic way? Please help

[@SaiGanesh314]

Waiting for a video on BFS algorithm.... :))

[@097_suryakantdhote9]

Will you be doing a video on hash maps?

[@handover007]

You teaches so nicely , your lectures sounds like music.

[@CodeBeauty]

I'm happy to hear that 🥰

[@uwebosse262]

perfect Explanation!

[@jamalparker4487]

How does the algorithm know to go back up a node after reaching a node with no left or right linked node?

[@danialsaud3189]

Iwanted to ask Where to learn about functions in headers file for c++ ?

[@QadimQarayev]

excellent

[@danielmartnutriologous]

I love you videos thank you for share you knowledge question do you have Patrion ?

[@CodeBeauty]

I don't have Patreon, maybe in the future, currently I only have BuyMeACoffee 😊😃☕

[@adanzavala4801]

From a brown-skinned Mexican, i say thanks, these videos of yours are absolutely BRILLIANT! They are helping me in my engineering classes, so again, thanks.

[@ishaankhatter6384]

Hey, Can you please post more videos of data structures?

[@mehdi-vl5nn]

is any difference between traversal and lookup ?

[@Mamunhasan-y8e]

please make graph algorithm video

[@abraarz2971]

Thank you!

[@MaySmithereen]

Please also do the breadth first search :)

[@mariacunha8508]

This video was SO helpful! I was struggling with this topic but it was so easy and simple to understand with you! Really appreciate you!

[@ASHWANIKUMAR-fc5pu]

kindly add more videos

[@ilham-t9y]

11:56 how do the program know that the root is passed to the next node?

[@spurti]

BFS please!

[@veslyju1984]

At the part printTree(Node* root){} printTree(root); why there is no pointer to pointer like insert in linkedlist? Like printTree(Node** root){} printTree(&root); I mean like this ,isn't root point to other ?

[@hbm293]

Hope everything is fine for you, following the earthquake in Stolac today!

[@CodeBeauty]

It was scary. Everything is fine with my family and all the people I know, but I read that there were some casualties. I hope that everything is okay with you, and I also hope that there will be no more earthquakes, because from what I read, a couple of them usually hits one after the other. That would be terrible 😰

[@Programming_Buddy1]

Love your videos!
