a) A 2-3-4 tree is a multiway tree with up to three keys and four children per node. In a 2-3- 4 tree, all insertions are made in leaf nodes, and all leaf nodes are on the same level. Explain what is in the name? The 2, 3, and 4 in the name 2-3-4 tree. b) In a 2-3-4 tree, on the other hand, nodes with a single link are not permitted. A node with one data item must always have two links, unless it's a leaf, in which case it has no links. A node with two links is called a 2-node, a node with three links is a 3-node, and a node with four links is a 4-node, but there is no such thing as a 1-node. Illustrate showing diagrams to show a 2-3-4 tree, which is a 2-node, a 3-node and a 4-node.

I need help in this question of Data Structure and Algorithms 1) Fill in the blanks a) Consider an AVL tree of height 0 with the smallest number of nodes possible. How many nodes this treehave? b) Consider an AVL tree of height 1 with the smallest number of nodes possible. How many nodes this treehave? c) Consider an AVL tree of height 2 with the smallest number of nodes possible. How many nodes this treehave? d) Consider an AVL tree of height 3 with the smallest number of nodes possible. How many nodes this treehave?
provided code:
3. In a B*-tree, there can be at most 4 search-key values in each node. Assume that the height of the B*-tree is 2. The height of the tree is the length of the path from the root to a leaf node. a) What is the maximum number of leaf nodes this tree can have? Answer: b) Let N1 be a node in the tree. N1 is neither a leaf nor the root. What is the minimum number of children that N1 can have? Answer:
5. Consider the tree given in the figure below and answer the following questions. a) b) c) R B A L M N GH I Which node is the root node? What is the level of the following nodes: A, B, Z, D, G, L? What is the height of the tree? Give all child nodes, the parent node and all sibling nodes of D.
6. Consider the following binary tree. a) b) 3 g) h) 5 8 5 1 2 10) 1 6 List the nodes visited with a preorder traversal. List the nodes visited with an inorder traversal. c) List the nodes visited with a postorder traversal. d) How many internal nodes are there? e) How many leaves are there? f) What is the maximum width of the tree? What is the height of the tree? What is the diameter of the tree?
7. Suppose preorder and inorder traversal order of the nodes of a binary tree is as follows: G, B, Q, A, C, K, F, P, D, E, R, H Q, B, K, C, F, A, G, P, E, D, H, R Preorder: Inorder: Draw the diagram of the binary tree.
The following three are the traversal sequence for preorder, inorder and postorder of a binary tree. 1. 33 27 77 25 55 53 67 43 88 99 II. 99 55 27 33 25 77 88 43 53 67 III. 27 33 55 77 25 99 88 53 43 67 a) Analyse which one is preorder, inorder and postorder. Explain and show your work. b) Based on question 6, build the tree and answer the following questions: 1. What is the node of level 1 left subtree ii. What is the node of level 1 right subtree iii. List all parents with only right leaf iv. List all leaves of the tree
I need the answer as soon as possible
me Portal (i) Write down the rules for the 3 types of tree traversals? (ii) Write all the three traversals for the tree given below? ( (iii) Are these 3 traversals possible only on a Binary Tree? Give reason for your answer ( hark R B M K e to search
Hey, same problem as my last question. What tree is that: Inorder: left tree, root, right tree Inorder: 8,2,4,6,11,10,7 How can 8 be on the left tree when 8<6.?
