In the above example, we have inserted a new node 30 to the right of right to node 10. We can see that after inserting a new node the balance factor of node 10 becomes -2 and the tree becomes unbalanced. To make
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 ...

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...

treat nil tree as height - 1 each node stores its height (DATA STRUCTURE AUGMENTATION) (like subtree size) (alternatively, can just store the difference in heights) Balance Worst when every node differs by 1 let = (min.) # nodes in height-h AVL tree ...
Thus, it is a data structure which is a type of self-balancing binary search tree. The balancing of the tree is not perfect but it is good enough to allow it to guarantee searching in O(log n) time, where n is the total number of elements in the tree. The insertion and deletion ...

二叉查找/搜索/排序树 BST (binary search/sort tree) 或者是一棵空树; 或者是具有下列性质的二叉树: (1)若它的左子树不空,则左子树上所有结点的值均小于它的根节点的值; (2)若它的右子树上所有结点的值均大于它的根节点的值; (3)它的左、右子树也分别为二叉排序树。 注意:对二叉查找树进行中序遍历,...
