I love Alvin's way of teaching. I loved his Dynamic programming video. Please ask him to make some more videos like Graphs and Trees.

@spaceface2288 2 года назад

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

@ehabahmedyassen Год назад

yup, q.next = c then b.next = q

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

@servantofthelord8147 8 месяцев назад

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!

@rebeccaburch3334 Год назад

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 🔥🔥🔥

Hey, you could have declared the array outside the function also and then you can use a single array for recursion.

@YuriG03042 Год назад

@AlThePal78 Год назад

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?

@ar2zee 2 года назад

Thank you so much for the course , as always it's awesome! Can somebody help me please and explain if instead of creating variable `currentHead` inside the function we'll just work with argument `head` and inside while loop just write `head = head.next` It's working in both cases but I want to see if it's any downside in this approach or something like that. Thanks in advance !

it's more complicated to read because of the cognitive overload, so for readability purposes it losses points.

I added a few cool touches to the sum problem: def get_sum_of_list(self): sum = 0 current = self.head while current is not None: if type(current.data) is int or float: sum += current.data current = current.next return sum def get_combined_strings(self): res = "" current = self.head while current is not None: if type(current.data) is str: res += current.data current = current.next return res
