进入正题：
|
||||
|
||||
题目中说要转换为一棵高度平衡二叉搜索树。这和转换为一棵普通二叉搜索树有什么差别呢？
|
||||
题目中说要转换为一棵高度平衡二叉搜索树。为什么强调要平衡呢？
|
||||
|
||||
其实这里不用强调平衡二叉搜索树，数组构造二叉树，构成平衡树是自然而然的事情，因为大家默认都是从数组中间位置取值作为节点元素，一般不会随机取，**所以想构成不平衡的二叉树是自找麻烦**。
|
||||
因为只要给我们一个有序数组，如果强调平衡，都可以以线性结构来构造二叉搜索树。
|
||||
|
||||
例如 有序数组[-10，-3，0，5，9] 可以就可以构造成这样的二叉搜索树，如图。
|
||||
|
||||
|
||||
|
||||
上图中，是符合二叉搜索树的特性吧，如果要这么做的话，是不是本题意义就不大了，所以才强调是平衡二叉搜索树。

|

|

在[二叉树：构造二叉树登场！](https://programmercarl.com/0106.从中序与后序遍历序列构造二叉树.html)和[二叉树：构造一棵最大的二叉树](https://programmercarl.com/0654.最大二叉树.html)中其实已经讲过了，如果根据数组构造一棵二叉树。
