Dec 21, 2022 · In this article, we will discuss the complexity of different operations in binary trees including BST and AVL trees. Before understanding this article, you should have a basic idea about Binary Tree, Binary Search Tree, and AVL Tree. The main operations in a binary tree are: search, insert and delete.

In this article, we are going to explore and calculate about the time and space complexity of binary search tree operations.

In this article, we will be discussing Time and Space Complexity of most commonly used binary tree operations like insert, search and delete for worst, best and average case. Table of contents: Introduction to Binary Tree; Introduction to Time and Space Complexity; Insert operation in Binary Tree Worst Case Time Complexity of Insertion

Use the Binary Search Tree below to better understand these concepts and relevant terminology. The size of a tree is the number of nodes in it (n n). A subtree starts with one of the nodes in the tree as a local root, and consists of that node and all its descendants.

We can write this as d = log2(n), where d tells us how much computation (how many iterations) we need to do (on average) to reach any node in the tree, when there are n nodes in the tree.

Mar 18, 2024 · Elementary or primitive operations in the binary search trees are search, minimum, maximum, predecessor, successor, insert, and delete. Computational complexity depends on the concept of the height of the tree , which we can informally define as the number of levels of which the tree is composed.

In a sorted array of n values, the run-time of binary search for a value, is O(log n), in the worst case. In the best case, the element you are searching for, is in the exact middle, and it can finish up in constant-time. In the average case too, the run-time is O(log n).

With a binary search tree you can read out the sorted list in Θ (n) time. This means I could create a sorting algorithm as follows. B <- buildBST(L) Sorted <- inOrderTraversal(B) return Sorted. With this algorithm I would be able to sort a list in better than Ω (nlogn). But as you stated this is not possible because Ω (nlogn) is a lower bound.

There are two basic operations that you can perform on a binary search tree: The algorithm depends on the property of BST that if each left subtree has values below root and each right subtree has values above the root.

Binary Search Tree property and differences between a binary tree and a binary search tree. Operations on BST, their algorithms and time and space complexity analysis. Uses and relationship with other data structures such as Dictionaries and priority Queues.
