Attached is an image of a binary tree: Write the order of the nodes visited in: An in-order traversal: A pre-order traversal: A post-order traversal: What is the height of the above binary tree?

Consider the following Binary Tree. root A B D E F C G H K If we perform an postorder traversal, which value is displayed FOURT Enter the node's label (A,B,C,D,E,F,G,H,K) in the space provided.

You are implementing a binary search tree class from scratch, which, in additionto insert, find, and delete, has a method getRandomNode() which returns a random node from the tree. All nodes should be equally likely to be chosen. Design and implement an algorithm for getRandomNode, and explain how you would implement the rest of the methods

In the binary search tree, write a function that takes in a root, p, and checks whether the tree rooted in p is a binary search tree or not. What is the time complexity of your function? def is_bst(self, p: Node):

The output of an in-order traversal of a binary tree is ACTION, and the output of the post-order traversal of the same binary tree is AIOTCN. What is the output of the pre-order traversal of the same binary tree? A. ATCONI B. NATCOI C. ACITNO D. NCATOI E. CAITNO

E5

For a binary tree, the pre-order traversal is H D A C B G F E the in-order traversal is: A D C B H F E G (A) Draw this binary tree (B) Give the post-order traversal

In java: binary tree Write a method called findTotalParents (, this method will find all the nodes that considered to be parents with any dependency and return the total number of parents. The public method shall not take any parameters, but the private method takes a BNode as a parameter, representing the current root.
