Tree Data Structure using Python

[@codingcart]

I have explained the whole code in 2nd lecture. If anyone is facing issue in this 1st lecture code please use the below code, add return statement when the node is None. if node is None: return self.createNode(data)

[@malyalasaiphaneendra6172]

I'm a beginner and trying hard to solve a leetcode problem regarding trees. But I don't have idea how a tree is constructed. Your explanation gave me complete structure of tree..... Thanks a lot for step by step explanation

[@astrobullivant5908]

Why is there a separate Node class when the Tree class doesn't even have a constructor?

[@satyamsrivastava3024]

Best explanation ever!! Thank you so much Sir for enlightening us 🙌❤️

[@satyamsrivastava3024]

Marvelous Explanation Sir. Just a humble request. I want to excel in card games such as- Bluff, Court piece, etc. Please post a tutorial on its algorithm. It'll be both fun & informative. Thanks.

Teacher, could you teach us with a N-ary tree? Please

[@techmentos]

You. have not initialised node any where. Can u plz explain more about node is None .

[@SatyendraJaiswalsattu]

It's initialized in the beginning, you can check the Node class constructor.

[@pardeep657]

is node a variable or instance? node.left is a variable and we are assigning Node(data) to it..howz that possible? Node(data) has 3 variables

[@SatyendraJaiswalsattu]

It's a instance, please have a look to class Node you will get it. Also visit part 2 of this lecture it will clear your all doubts.😊

[@RiyaBhawsar-b9i]

@codingcart can you please share link of linkedlist and array here, i can not find that.

[@adritaanwar2279]

I didn't understand why "return node" is returning the very first node every time because the node value is changing at every recursion. Someone please help.

[@codingcart]

Coz the head node should be kept hinged, suppose you are going to iterate through the list and if you don't have the head node then how will you proceed. So for going for any operation we have to start with head only. That's why head is kept hinged or safe.😊

[@adritaanwar2279]

@@codingcart Actually I understood why the head node is hinged. My question is how is it hinged since the node value changes in the recursive process.

[@codingcart]

Each time new node is added to their respective position by going through condition check, head node is not being changed. Just take few inputs and dry run on paper you will get this one.if you still face problem you can ping on whatsapp 😊
