Data structures: Linked List implementation of Queue

[@Naveenkumar-sn1et]

Nobody can explain this much clearly on a topic like Data Structure. Your videos are still continuing to be a hope for many students around the world

[@fcortesjp]

Wow.. amazing... thank you so much.. It can't be clearer.. and the considerations about time of execution are a plus on this video. Awesome job.. I'm taking this class at a University in Colombia (south america) but the material I have to study from is light years away from your considerations and dynamics seen on your video.. all my kudos to you!.. this just furthers my admiration from India

[@mycodeschool]

Thanks a lot Francisco Cortes for your encouraging words. :)

Frankly I have never seen an explanation so easy and simple like what you have done in this video , its as u were reading my thoughts , any question that pops into my mind , I find you answering it , thank you one more time and I hope you see my comment after all these years and make ur day

[@hehhehdummy]

You teach at such a high quality. I'm thankful that you have made these videos. Your voice is pleasant as well.

[@ShankarRam23]

These video lectures rival the ones produced by several other foreign channels and outclasses them in several aspects. Best CS channel on youtube.

[@rraj2095]

the best and most precise explanation till far i've seen on internet..thanks a ton

[@cjbantillo8142]

This topic made me cry, but thank you so much for having these lectures for free it really helps

[@aptitudepointiit-bhu5358]

This channel made the basic concepts crystal clear, thus all these follow-up questions are self-doable now. 💛

[@pritammane1594]

Your linked list explanations are too gud. U just saved my tomorrow's sem exam. THANK YOU SO MUCH !!!!!!!!!

[@nirajabcd]

Beautiful! I am learning a lot from your videos. I have tired many books and other online courses but they can't be matched with yours. Hats off to you. Can't wait for more tutorials on graphs and other advanced topics.

[@davidhilbert6830]

Your one video is enough to understand. You are really good teacher. I should really thank you , you have actually helped me clear my college practicals. Your way of understanding is very good, I have seen many videos on KZbin yours was the best. I will recommend your videos for my friends as well. I kept on reading COMPUTER SCIENCE BY SANGEETA ARORA, THE BOOK IS A WASTE.

[@harshupreti1526]

isnt it sumita arora ?? XD just asking !!

[@S3verance]

thats what i was thinking to lol

[@divyanshagarwal993]

Pleasant voice,crystal clear explanation. Why can't my teacher be like this?

[@aupairindo4085]

The best java tutorial on youtube! great job! Many greetings from Schwitzerland!

[@aravindrajeev4594]

Exactly what I needed before my practical exam🙌🙌👌👌😌

[@JZX619]

This playlist is really amazing. God bless you for helping students with their careers.

[@Gurpreetsingh-fz4fq]

bro he is no more.....

[@SuperJAIMISH]

That was explained way better than any teacher that has ever taught me! Thanks alot mate!

[@VictorJunyiWang]

Thanks for the great uploading, succinct and easy to grasp. Just one typo in the code : struct Node* temp = (struct Node*)malloc(sizeof(struct Node*)); should be: struct Node* temp = (struct Node*)malloc(sizeof(struct Node)); I believe this is just a typo, however, might give confusion to beginners. :)

[@mycodeschool]

Yeah.. it should be sizeof(struct Node) .. Thanks for pointing out. :)

[@manvendranagaich7377]

Thanks a lot , u have been able to put across the complex subject in a very subtle and simplified manner, it has saved a lot of time.

[@magadheera7]

You guys are awesome!! I can bet these are the best free lessons on the internet.. Your touch of underlying concepts and basics make you unique.. You will be big ones some day.. Thank you!!

[@shekharsharma3329]

I am preparing for my college placement and your videos are a great source to learn.

[@marucado2539]

You really helped me! Thank you very much. Even i don't know english very well, i could understand you. Thank you!!

[@mohitdaga2356]

Amazing tutorial. This is the best data structure series on the Internet. But,there is one thing I feel you should check in the dqueue function, when (front==rear), this might also mean that there is ONE ELEMENT present in the queue. So first we need to delete this and then (front=rear=NULL).

[@sindhug7130]

when you say "might also mean", is there a different meaning of front==rear? I mean does it mean anything else apart from the fact that there is only one node in the queue?

[@ruis2345]

Thank you for explaining these abstract process in a intuitive way. So amazing course.

[@RajAnand2311]

Thanx for putting on this video. You just saved me from failing in xams.

[@shohag402]

All of your data structure videos are awesome. It could not have been better in my sense. I am eagerly waiting for your Graph tutorials...........

[@piyaliroy8485]

wish he was a teacher at my college.. love his videos !! thanks a LOT !!

[@mrigendrapatel]

Crystal clear explanation. You rock man!!! :)

[@KimberleyNaris]

this is so much easier than how my lecturer taught it...thanks a lot😊

[@zokna]

If I am correct, the if(front==NULL && back==NULL) check in Enqueue() can be reduced to simply check the following condition if(front==NULL). This would also make the check at line 4 at 12:27 obsolete, since the "front" pointer will automatically be set to NULL, when the last node is dequeued, given the fact that the "last node"->next = NULL. This is of course only true if we perform a IsEmpty() check at the first line in Dequeue().

[@joshuakoehler6457]

A note to those who attempt the code and test. There is an error in his Enqueue function. For allocating space for a new link, the line should read struct Node* temp = malloc(sizeof(struct Node)); The cast on the right side (e.g. struct Node* next to malloc) is redundant. The other issue (a much bigger one) is that he malloced a pointer to a structure, instead of the structure itself. It should read malloc(sizeof(struct Node)) NOT struct Node* ! This will only allocate enough memory for a POINTER to a link, and not the link itself, which will cause an error with some compilers (Visual Studio C++ included). This thread explains this undefined behavior stackoverflow.com/questions/59418706/heap-corruption-detected-in-visual-studio-but-program-runs-fine-in-another-c-co

[@tenealaspencer4150]

This was awesome! The explanation of time complexity was great as well!

[@surajbisht4111]

brother your videos really helped me a lot with data structure.. keep making these videos..

[@MrBalakoteswar]

I loved your way of explanation, simply super excited.

[@shama.niyazi]

Thank you so much brother 🙏🙏 .. I was struggling 😭... Now understanding 😁🙏

[@ntlzz93]

when you finished any subject , you should have supplied more applications for this lesson . Like when finished lesson about stack or other lesson , you could introduce about application of stack such as Tower of Ha Noi , 8 Queens. ( I don't know exactly ) Thank you very much about your tutorials .

thank you brother for the huge help...ur videos are so smooth to grasp

[@vamshitangudu1728]

hi, in Data structures: Linked List implementation of Queue, I think the implmentation of en-queue has might need to be modified. the video shows struct Node* temp = (struct Node*)malloc(sizeof(struct Node *)); but instead it should be struct Node* temp = (struct Node*)malloc(sizeof(struct Node));

[@ar_tushar]

Yes! u r right!

[@abhishekahirrao4271]

13:27 3rd line of the dequeue function it should be - if(rear=NULL) return; as the queue then would be unfilled. Front=NULL doesn't make any sense.

[@Dibyendu_K]

Its very helpfull......Thanks alot,,,,,,,

[@HuthaifaMady1992]

Simple and awesome, Thank you ,,

[@akniazi001]

Hi, this video lecture i think need a little modification, AS here, front and rear are pointing the same position where in definition always memory size is N-1 and if front and rear is equal at the start means that queue is empty and if it found during insertion it shows the overflow message. so always one cell will be empty where our front pointer will point. But in video both are pointing to one cell where it has value as well.

[@theherbalistsassistant]

You, my Good sir, are awesome!! :D
