Given an array where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees ofeverynode never differ by more than 1. Example: Given the sorted array:...
二叉搜索树(Binary Search Tree,简称BST)也称为二叉查找树、有序二叉树(Ordered Binary Tree),或排序二叉树(Sorted Binary Tree)。二叉搜索树是一颗空树,或具有以下性质的二叉树: 如果任意节点的左子树不为空,则左子树上所有节点的值小于它的根节点的值。

data in a non-linear fashion. After discussing the properties of binary trees, we'll look at a more specific type of binary tree—the binary search tree, or BST. A BST imposes certain rules on how the items of the tree are arranged. These rules provide BSTs with a sub-linear search ...
Introduction Arranging Data in a Tree Understanding Binary Trees Improving the Search Time with Binary Search Trees (BSTs) Binary Search Trees in the Real-WorldIntroductionIn Part 1, we looked at what data structures are, how their performance can be evaluated, and how these performance ...
Given an integer arraynumswhere the elements are sorted in ascending order, convert it to a height-balanced[^1] binary search tree. Before we start off, there are some important observations: numsis already sorted. AnArrayis given as aninput. So, accessing an element will be a constant-tim...
