To identify all the nodes that are considered to be leaves, or the nodes that do not rely on any BNodes, you may create a new method and call it findTotalleaves (). The private method takes a BNode representing the current root as an argument, but the public one does not.
In a doubly linked list the first class is Node which we can create a new node with a given element. Its constructor also includes previous node reference prev and next node reference next.
make a node object for the new element. Check if the index >= 0.If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null.
implement these 3 methods: insert_at_index(), delete_at_end(), display(). use these three functions above
use this to name the items
1. insert_to_empty_list()2. insert_to_end()3. insert_at_index()
4. delete_at_start()
5. delete_at_end() .
6. display()
let the output be
OUTPUT:
The list is emptyElement is: 3Element is: 10Element is: 20Element is: 30Element is: 35Element is: 38Element is: 40Element is: 50Element is: 60

Sorting
Create a MyLinkedList class with inner Node class, data fields, and the insert(element) method.
Implement a toString method to return all nodes in MyLinkedList.
Implement a recursive sorting and a non-recursive sorting method.

- In java: binary tree Write a method called findTotalleaves (), this method will find all the nodes that considered to be leaves, which is they have no BNode dependencies.

- You are creating from scratch a binary search tree class with the methods insert, find, and delete in addition to the method getRandomNode(), which retrieves a random node from the tree. There should be an equal chance of selecting each node.
