Abstract Data Types vs. Data Structures | ADT vs. DS | Geekific

This video is absolutely incredible and underrated gem. This is how we not only learn but remember. Thank you so much.

[@cornelialorenzo2038]

The way you explained the differences between ADT and DS were easy to understand. I like the analogy because it had given me a concrete image of how ADT and DS work. Thank you!

[@tadiwoskebede3798]

Best explanation!

[@skylakaris9811]

Thank you so much; i love how you explained it

[@MrChaluliss]

Not going to lie, the first 3 minutes of the video were not helpful at all for me, But starting at 2:59, those brief definitions were exactly what I wanted to hear. Not to critique too much, but I would put these definitions up front in the future, and the analogous examples afterword's in the future. (that is my personal preference for learning these kinds of topics at least)

[@geekific]

Will keep this in mind for the future. Thank you :) Glad you liked it!

Okay so lets say you implement a stack with nodes. Can you say the stack is a Data Structure then but until it is implemented it is an ADT?

[@geekific]

The idea of the stack; i.e. LIFO structure, or the fact that you can only access the top node, etc... represent the definition of the stack, the WHAT, the abstraction of these ideas, the interface, the ADT. When you dive in the implementation details i.e. nodes, array, etc. you start answering HOW this stack is implemented, then you'll be talking about the DS. Hope this answers your question :) Cheers!

[@kakashi99908]

@@geekific Thanks it helps! I was also wondering why is it that we need a separate node class if we want to use it to implement an ADT, like why can't the node be part of the Stack class itself? I only see it done as two separate classes. Is it because a class cant store itself as a collection?

[@geekific]

@@kakashi99908 I am not sure I really got you, but the Stack has to reference the root node only, this will be enough to access the structure. As long as the properties of a Stack defined in the ADT are met, you can implement it however you like, these are just implementation details :)
