What are the key differences between BST and AVL trees in terms of their structure and performance?

BST (Binary Search Tree) and AVL (Adelson-Velsky and Landis) trees are both types of binary trees used for storing and searching data. The key difference lies in their structure and performance. BSTs are simple binary trees where each node has at most two children, and the left child is smaller than the parent while the right child is larger. This structure allows for efficient searching, insertion, and deletion operations. However, if the tree is not balanced, it can degrade into a linked list, leading to slower performance. On the other hand, AVL trees are a type of self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one. This balancing property ensures that the tree remains relatively balanced, leading to faster search, insertion, and deletion operations compared to BSTs. However, maintaining this balance requires additional overhead, making AVL trees slightly slower in terms of performance compared to BSTs for some operations.


How can one determine the height of a Binary Search Tree (BST)?

The height of a Binary Search Tree (BST) can be determined by finding the longest path from the root to a leaf node. This can be done by starting at the root and recursively calculating the height of the left and right subtrees, then taking the maximum of the two heights and adding 1 for the current node. This process is repeated until all nodes are accounted for, resulting in the height of the BST.


What is the process and significance of using breadth first search (BFS) in a binary search tree (BST)?

Breadth First Search (BFS) is a method used to traverse or search a binary search tree (BST) level by level, starting from the root. This means that all nodes at the same level are visited before moving on to the next level. The significance of using BFS in a BST is that it allows for finding the shortest path between nodes and can be helpful in algorithms like finding the shortest path in a graph or determining if a path exists between two nodes.


What are the key differences between a heap and a binary search tree (BST)?

A heap is a complete binary tree where each node has a value greater than or equal to its children (max heap) or less than or equal to its children (min heap). A binary search tree is a binary tree where the left child of a node has a value less than the node and the right child has a value greater than the node. The key difference is that a heap does not have a specific order between parent and child nodes, while a binary search tree maintains a specific order for efficient searching.


What are the key differences between a binary search tree (BST) and a heap data structure, and how do these differences impact their performance and use cases in various applications?

A binary search tree (BST) is a data structure where each node has at most two children, and the left child is less than the parent while the right child is greater. This allows for efficient searching, insertion, and deletion operations. On the other hand, a heap is a complete binary tree where each node is greater than or equal to its children (max heap) or less than or equal to its children (min heap). Heaps are commonly used for priority queues and heap sort. The key differences between BST and heap are: BST maintains the property of ordering, while heap maintains the property of heap structure. BST supports efficient searching, insertion, and deletion operations with a time complexity of O(log n), while heap supports efficient insertion and deletion with a time complexity of O(log n) but searching is not efficient. BST is suitable for applications where searching is a primary operation, while heap is suitable for applications where insertion and deletion are more frequent. In summary, the choice between BST and heap depends on the specific requirements of the application. If searching is a primary operation, BST is preferred. If insertion and deletion are more frequent, heap is a better choice.

IS AVL-Tree IS binary tree?

An AVL tree is another balanced binary search tree. Named after their inventors, Adelson-Velskii and Landis, they were the first dynamically balanced trees to be proposed. Like red-black trees, they are not perfectly balanced, but pairs of sub-trees differ in height by at most 1, maintaining an O(logn) search time. Addition and deletion operations also take O(logn) time.Definition of an AVL treeAn AVL tree is a binary search tree which has the following properties: The sub-trees of every node differ in height by at most one.Every sub-tree is an AVL tree.


What are the applications of avl tree?

Binary Search Tree and AVL Tree are dictionary data structures. They are used for many search operations and also those operations where data is constantly inserted and deleted. AVL trees provide a better efficiency than BST as they maintain their upper bound of O(n*log n) through rotations.Eg: the map and set library in c++ isimplementedusing trees.


What is the difference between avl tree and binary tree?

A binary tree is a tree data structure in which each node has at most two children. Typically the child nodes are called left and right. One common use of binary trees is binary search trees; another is binary heaps. A binary search tree (BST) is a binary tree data structure which has the following properties: ->each node has a value; ->a total order is defined on these values; ->the left subtree of a node contains only values less than the node's value; ->the right subtree of a node contains only values greater than or equal to the node's value. An AVL tree is a self-balancing binary search tree. In an AVL tree the heights of the two child subtrees of any node differ by at most one, therefore it is also called height-balanced. Lookup, insertion, and deletion all take O(log n) time in both the average and worst cases. Additions and deletions may require the tree to be rebalanced by one or more tree rotations.

What is the use of AVL tree?

Binary Search trees offer improved average case performance for searching. However, if they are unbalanced their search performance degrades to that of a linked list. AVL trees guarantee that the difference in height of any two subtrees rooted at the same node will be at most one. This guarantees an asymptotic running time of O(log(n)) as opposed to O(n) in the case of a standard bst.


What is purpose of AVL tree?

AVL TreesIn computer science, an AVL tree is the first-invented self-balancing binary search tree. In an AVL tree the heights of the two child subtrees of any node differ by at most one, therefore it is also known as height-balanced. Lookup, insertion, and deletion are all O(log n) in both the average and worst cases. Additions and deletions may require the tree to be rebalanced by one or more tree rotations. The AVL tree is named after its two inventors, G.M. Adelson-Velsky and E.M. Landis, who published it in their 1962 paper "An algorithm for the organization of information."The balance factor of a node is the height of its right subtree minus the height of its left subtree. A node with balance factor 1, 0, or -1 is considered balanced. A node with any other balance factor is considered unbalanced and requires rebalancing the tree. The balance factor is either stored directly at each node or computed from the heights of the subtrees.

What is the difference between extended binary tree and a binary search tree?

A strictly binary tree is one where every node other than the leaves has exactly 2 child nodes. Such trees are also known as 2-trees or full binary trees. An extended binary tree is a tree that has been transformed into a full binary tree. This transformation is achieved by inserting special "external" nodes such that every "internal" node has exactly two children.


Does binary search tree take much time than the list to delete or insert an element?

No. Binary search tree will take less time to delete or insert an element. While deleting from list, more time will be required to search for the element to be deleted but BST will work faster if the no. of elements are more. Plus it depends upon which element is to be deleted and where the element is to be added. But the average time to perform these operations will be less in BST as compared to lists

What is the binary search tree worst case time complexity?

Binary search is a log n type of search, because the number of operations required to find an element is proportional to the log base 2 of the number of elements. This is because binary search is a successive halving operation, where each step cuts the number of choices in half. This is a log base 2 sequence.
