Imagine a set implementation which uses heaps, instead of binary search trees. How would the performance of such a data structure differ from the actual implementation of AVL tree?
Homework Answers
A set which is using heap implementation takes O(log n) for insert operation but it takes O(n) for searching for an item. but with AVL implementation of a set, it only takes O(log n) for insert, search, delete operations. so, using AVL implementation for a set, improves it's performances in regards to searching for items in set.

Consider the __init__ constructor method for the Python implementation of a node within a binary tree. The binary tree will aim to require minimal space by having only one tree node per search key. How would this constructor method differ between a Set and a Map? How might this constructor method differ between a Map and a Multi-map? How might this constructor method differ between a Set and a Multi-Set?

For the set of keys [37, 24, 29, 66, 17, 82, 43], draw binary search trees of height 2, 4, and 6. Argue that since sorting n elements takes Ω(n log n) time in the worst case in the comparison model, any comparison‐based algorithm for constructing a binary search tree from an arbitrary list of n elements takes Ω(n log n) time in the worst case. When node z in TREE‐DELETE has two children, we could choose node y as...

C++ Vectors and Binary Search Trees • Write a program that takes from the user n integers and stores them a vector of int. Then, create a function insert After that takes first Value and second Value. This function searches for each occurrence of first Value in the vector and insert the second Value after it in the same vector. The first and second values are taken from the user. • Create another function that creates a Binary Search Tree...
A balanced binary tree is a binary tree structure in which the left and right subtrees of every node differ
Data structures C++1- A balanced binary tree is a binary tree structure in which the left and right subtrees of every node differ in height by no more than 1 Out of the following choices, which is the minimum set of nodes, if removed, will make the BST balanced?2- Which of the following is true for Red-Black Trees ? Select all choices that apply! Select one or more: a. For each node in the tree, all paths from that node to any leaf nodes contain...

Instead of using a linked list to resolve collisions, as in separate chaining, use a binary search tree. That is, create a hash table that is an array of trees. To display a small tree-based hash table, you could use an inorder traversal of each tree. The advantage of a tree over a linked list is that it can be searched in O(logN) instead of O(N) time. This time savings can be a significant advantage if very high load factors...

Questions 1a–d are about developing an efficient implementation of a Set that combines the advantages of a hash table and a balanced binary search tree. In particular, the search function for your data structure should have O (lg n ) worst case complexity and Θ(1) expected case complexity, and it should not be limited to values in a small range (as a bit vector would). (a) Describe how you would store data values in memory. (b) Give pseudocode for how...
