In the above example, we have inserted a new node 20 to the left of the right to node 30. We can see that after inserting a new node the balance factor of node 30 becomes -2 and the tree becomes unbalanced. To make this tree balanced tree we will apply RL Rotation on the tree. ...
AVL tree stands for Adelson, Velskii & Landis Tree, and it can be explained as an extension of the binary search tree data structure. Though it’s similar to a binary search tree, there is one highlight of a difference that is the height of the tree value should be <=1, and unlike ...

插入操作是否破坏了平衡条件是通过判断该节点左右子树高度来判断,因此AvlTree的节点相较于二叉查找树增加了节点高度的变量,其中空子树高度为-1,只有一个节点的子树高度为0,每次插入操作完成后要重新更新被影响节点的高度。 三、修复平衡 ①如果1、4情况破坏了平衡条件需要对该节点进行一次单旋转。以情况1为例:首先把...
本文使用C++实现一个基于AVLTree实现的map/set,不同于网上大部分的实现,本文争取按照C++STL风格来编写。 前言 其实网上关于数据结构的文章已经满大街了,但是大多数的实现都非常简单,虽然有些使用Java/C#/Python版本的代码甚至可能和其标准库相差无几,但是C++不一样,C+

平衡二叉树(Balanced Binary Tree)又被称为AVL树(有别于AVL算法) 在AVL中任何节点的两个儿子子树的高度最大差别为1,所以它也被称为高度平衡树,n个结点的AVL树最大深度约1.44log2n。查找、插入和删除在平均和最坏情况下都是O(logn)。增加和删除可能需要通过一次或多次树旋转来重新平衡这个树。这个方案很好的解...
