1. Construct an AVL tree for the list C, S, U, M, B, W, I, N. Use the alphabetical ascending order of the letters and insert them successively starting with the empty tree. Your answer should present the rotation operations clearly for each letter addition.
2. Present an insertion order for the keys C, S, U, M, B, W, I, and N that leads to a 2-3 tree of height 1. In the problem, you should use the alphabetical ascending order of the letters to construct the 2-3 tree. Note that the height of an empty tree is height -1. And the height of a tree with only a root node is 0.

a. Construct a 2-3 tree for the list C, O, M, P, U, T, I, N, G. Use the alphabetical order of the letters and insert them successively starting with the empty tree. b. Assuming that the probabilities of searching for each of the keys (i.e., the letters) are the same, find the largest number and the average number of key comparisons for successful searches in this tree.

The INORDER traversal output of a binary tree is U,N,I,V,E,R,S,I,T,Y and the POSTORDER traversal output of the same tree is N,U,V,R,E,T,I,S,I,Y
a. The INORDER traversal output of a binary tree is U,N,I,V,E,R,S,I,T,Y and the POSTORDER traversal output of the same tree is N,U,V,R,E,T,I,S,I,Y. Construct the tree and determine the output of the PREORDER traversal output. b. One main difference between a binary search tree (BST) and an AVL (Adelson-Velski and Landis) tree is that an AVL tree has a balance condition, that is, for every node in the AVL tree, the height of the left and right subtrees differ by at most 1....

True or false? (a) An insertion in an AVL tree with n nodes requires Θ (log(n)) rotations. (b) A set of numbers are inserted into an empty BST in sorted order and inserted into an empty AVL tree in random order. Listing all elements in sorted order from the BST is O (n), while listing them in sorted order from the AVL tree is O (log(n)). (c) If items are inserted into an empty BST in sorted order, then the...

PYTHON QUESTION... Building a Binary Tree with extended Binary Search Tree and AVL tree. Create a class called MyTree with the methods __init__(x), getLeft(), getRight(), getData(), insert(x) and getHeight(). Each child should itself be a MyTree object. The height of a leaf node should be zero. The insert(x) method should return the node that occupies the original node's position in the tree. Create a class called MyBST that extends MyTree. Override the method insert(x) to meet the definitions of a...
