Question 8 options: Identify imbalance and rebalance the following BST into an AVL tree. Assume the node with key 2 was inserted last.
Exercise 3: Multi-way Trees A way to reduce the height of tree and ensure balance is to allow multiple children of nodes. In your class you learned 2-3 trees which allows up to 2 keys in a node, and the number of children is equal to the number of keys + 1. B-trees extend this concept to any arbitrary number of keys (usually number of keys is even and number of children (equal to number of keys+1) is odd). Assume we want to design a 5-way B-Tree. This will mean that there can be maximum 4 keys in a node, and if the number of keys becomes 5, we can split it into two (the same way we split 2-3 tree when number of keys becomes 3). Design a 5-way B-tree. Starting with an empty tree, insert the following keys in order. 2, 3, 5, 7, 10, 50, 22, 44, 45, 55, 66, 68, 70, 17, 6, 21, 67

TREE-DELETE is broken into three cases.Case 1: z has no children.• Delete z by making the parent of z point to NIL, instead of to z.Case 2: z has one child.• Delete z by making the parent of z point to zís child, instead of to z.Case 3: z has two children.• zís successor y has either no children or one child. (y is the minimumnodeówith no left childóin zís right subtree.)• Delete y from the tree (via Case 1 or 2).• Replace zís key and satellite data with yís.✄ Determine which node y to splice out: either z or zís successor.
Consider the rooted tree shown below. Which of the following statements are true? a O h b e i с f d 9 The sub-tree rooted at the node "d" contains the nodes "d", "f" and "g". The parent of "b" is "e". The height of the tree is 2. The nodes "h", "i", "c", "f" and "g" are at the same level. The node "i" is a leaf node. The node "a" is an ancestor of the node "e". The depth of "b" is 2. The node "b" is a sibling of the node "d". The height of the tree is 3.
when the successor is the left child of the node to be deleted. What are the steps followed by algorithm for performing this operation.
