Convert Sorted Array to Binary Search Tree(将一个有序数组转换成一颗二叉搜索树)

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 of every node never differ by more th…

convert sorted list to binary search tree(将有序链表转成平衡二叉搜索树)

Given a singly linked list 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 of every node never diffe…

[LeetCode] Convert Sorted Array to Binary Search Tree 将有序数组转为二叉搜索树

Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 这道题是要将有序数组转为二叉搜索树,所谓二叉搜索树,是一种始终满足左<根<右的特性,如果将二叉搜索树按中序遍历的话,得到的就是一个有序数组了.那么反过来,我们可以得知,根节点应该是有序数组的中间点,从中间点分开为左右两个有序数组,在分别找出其中间点作为原中间点的左右两个子节点,这不就是是二分查找法的核…

LeetCode 108. Convert Sorted Array to Binary Search Tree （有序数组转化为二叉搜索树）

Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 题目标签:Tree 这道题目给了我们一个有序数组,从小到大.让我们把这个数组转化为height balanced BST. 首先来看一下什么是binary search tree: 每一个点的left < 节点 < right, 换一句话说,每一个点的值要大于左边的,小于右边的. 那么什么是heigh…

108 Convert Sorted Array to Binary Search Tree 将有序数组转换为二叉搜索树

将一个按照升序排列的有序数组,转换为一棵高度平衡二叉搜索树.此题中,一个高度平衡二叉树是指一个二叉树每个节点的左右两个子树的高度差的绝对值不超过1.示例:给定有序数组: [-10,-3,0,5,9],一种可行答案是:[0,-3,9,-10,null,5],它可以表示成下面这个高度平衡二叉搜索树:      0     / \   -3   9   /   / -10  5详见:https://leetcode.com/problems/convert-sorted-array-to-binary…
