Hands down the best explanation for linked list. It finally clicked on me after 3 days banging my head against the wall. His algorithms are way more intuitive, both iterative and recursive versions, much much more than what other instructors talked about. Thank you!

08:25 one small correction, the order of inserting a node to a linkedlist is that the node you wish to enter has to point first to the node and then you have to take node b to point on node q, if you start by pointing b to q first you will lose all the data of c and d. Great video !! loved it

For the iterative Zipper implementation, we need a null check for head1 (ideally for head2 as well). if(head1 === null) return head2; if(head2 === null) return head1;

I just realized watching theory tutorials in other languages actually makes learning so much more intuitive, since you can't just blindly copy. You're forced to understand how your language works, and you're forced to implement those ideas without really being able to "cheat". Wow. I'm gonna start watching C tutorials and do them in python. I'm about to hit 10x developer once I understand all this

This is a very good point. I never realized this. This whole time I was trying to avoid tutorials in different languages, not realizing that they were the key to helping my solidify my understanding. Good observation!

for zipperlist iterative approach, when you add the rest of the list that is leftover tail isn't reassigned to be the new tail. In this case, you're just using "tail" as a pointer to the current end of the constructed list. And tail isnt assigned at all in the recursive solution. Would there be an extra step to iterate through the leftover list to the end and reassign tail? Thanks for your great videos 🔥🔥🔥

this is literally the best video I seen on this. However, you said it can be anything in the data. However, in C# and Java would be different. it would have to be what you choose it to be because you have to initialize the type of data it has to enter so all the nodes would have integers. Am I right or am I wrong?
