Implement an iterator for a binary search tree (BST) that returns the set of all values stored in the tree in sorted order (from least to greatest). Important: Both your hasNext () and next () implementations – as well as the constructor – should operate in O(h) time (worst-case), where h is the height of the tree. You do not need to implement the remove () method. You may assume that each value stored in the BST is unique.

In python. Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…

Implement a priority queue using a heapordered binary tree, but use a triply linked structure instead of an array. You will needthree links per node: two to traverse down the tree and one to traverse up the tree. Yourimplementation should guarantee logarithmic running time per operation, even if nomaximum priority-queue size is known ahead of time.
