Data Structures: Stacks and Queues

Learn the difference between linear data structures stacks and queues. This video is a part of HackerRank's Cracking The Coding Interview Tutorial with Gayle Laakmann McDowell.

You explained this better in 5 mins, than my professor could in 2 hours! Thank you so much!

[tannerbarcelos]

It is funny when you get a pretty good foundation in your intro to comp sci courses how easily it is to understand these data structures. Then again, Gayle is an amazing teacher! Not a luxury we all get with college, lol.

awesome vid. you are the first person who has really explained the coding of this algorithm in a manner i actually understood.

[tan]

Thank you very much ma'am. Stacks and Queue's have been stressing me out for the longest, but now I have actually taken the time to sit down and understand them and they are actually fairly simple, at the mention of pointers, I used to tremble, but now I realise that I have got nothing to fear at all!

Thank you so much ma'am! You're an inspiration for new tutors like me🙏💙💙💙

[frankchen]

Your videos are always so straight-foward!

[englotv]

this is true coding. you helped me understanding sta
cks

Greate video!
One suggestion - When implementing a Stack, it makes more sense to call the Node's pointer "prev" than "next", because logically it doesn't point to the one that comes after him :)

Thanks for this, you made the code seem so much simpler

[joyalmeida]

can you suggest me a title for a project which uses data structure in c. I need a project which uses link list/ stack / queues

[rumelia]

This series of Data Structures is great! Succinct, clear, and to the point. I only wished they used C++ since I got a final of it coming up :D

[robertbonham]

Currently working on a class project where we can choose to either do stack or queue, which one would be better implement/ use. Stacks or Queues?

[kataya]

does it make sense that node is a static class, since we're making instances of the node with different data ?

[danielabengona]

Where do you think it would be applicable to use them in some certain programs?

[theSDE]

Thanks for these easy videos to undertand.

[shibinfrancis]

How did you add first tail? If(head == null){ head = node; tail ?}

[hasansakib]

Sometimes i wonder how many subscribers did you get after these wonderful lectures??

[silvershocknicktail]

I see so many tutorials for coding using this same doodling/animation software, but I don't recognise it. What is it?

[mohdbilal]

very well understood.Thanks mam from India 🇮🇳

[luiscarlosquesadasequeira]

Can anyone explain at 3:33, in the remove method, why the tail need to be set to null after updating/removing the head? L36.
