平衡二叉树(Balanced binary tree)是由阿德尔森-维尔斯和兰迪斯(Adelson-Velskii and Landis)于1962年首先提出的,所以又称为AVL树。
定义:平衡二叉树或为空树,或为如下性质的二叉排序树:
(1)左右子树深度之差的绝对值不超过1;
(2)左右子树仍然为平衡二叉树.
平衡因子BF=左子树深度-右子树深度....

检测一个树是否平衡,不需要求出高度,而是从底到顶检测是否平衡,这样才算法时间复杂度为O(n)。但是需要额外的O(logn)的空间

题目:
Given an array where elements are sorted in ascending order, convert it to a height balanced BST.
我的解法:
(1)算法思想:
二分法,数组的中间点为根节点,然后递归。
(2)代码如下:
