LeetCode: Convert Sorted Array to Binary Search Tree 解题报告

Convert Sorted Array to Binary Search Tree

Given an array where elements are sorted in ascending order, convert it to a height balanced BST.

SOLUTION 1：
使用递归解决。

base case: 当索引值超过时，返回null.

递归主体：构造根节点，调用递归构造左右子树。并将左右子树挂在根节点上。

返回值：返回构造的根节点。

LeetCode Convert Sorted List to Binary Search Tree 解题报告

Given a singly linked list where elements are sorted in ascending order, convert it to a height balanced BST. 从给定的有序链表生成平衡二叉树. 解题思路:最容易想到的就是利用数组生成二叉树的方法,找到中间节点作为二叉树的root节点,然后分别对左右链表递归调用分别生成左子树和右子树.时间复杂度O(N*lgN) AC代码: public class Solution { ListNode

原题地址:http://oj.leetcode.com/problems/convert-sorted-array-to-binary-search-tree/ 题意:将一个排序好的数组转换为一颗二叉查找树,这颗二叉查找树要求是平衡的. 解题思路:由于要求二叉查找树是平衡的.所以我们可以选在数组的中间那个数当树根root,然后这个数左边的数组为左子树,右边的数组为右子树,分别递归产生左右子树就可以了. 代码: # Definition for a binary tree node # class

LeetCode: Convert Sorted Array to Binary Search Tree [108]

[题目] Given an array where elements are sorted in ascending order, convert it to a height balanced BST. [题意] 给定一个已排序的数组(不存在重复元素),将它转换成一棵平衡二叉搜索树. [思路] 由于平衡二叉树要求左右子树的高度差绝对值相遇等于1,也就是说左右子树尽可能包含相同数目节点. 则使用二分法来解本题即可. [代码] /** * Definition for binary tree *

Given an array where elements are sorted in ascending order, convert it to a height balanced BST. 原题链接:https://oj.leetcode.com/problems/convert-sorted-array-to-binary-search-tree/ 题目:给定一个升序排列元素的数组,将其转换成高度平衡的二叉树. 思路:已经排序.则从中间劈开,中间元素为树的根,左右递归构建. public

[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
