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 ...
看起来很难，但是仔细想一下，实质就是二叉树的中序遍历的问题，中序遍历有递归和非递归(至少两种写法)。 递归： 非递归 Divide and Conquer 思路和中序遍历很类似，但是代码写起来有一点不一样。感觉这种方法思路更加清晰。 ...
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 ...
Given the root node of a binary search tree (BST) and a value. You need to find the node in the BST that the node's value equals the given value. ...
Return the root node of a binary search tree that matches the given preorder traversal. (Recall that a binary search tree is a binary tree where ...
Given an array of numbers, verify whether it is the correct preorder traversal sequence of a binary search tree. You may assume each number ...
1：题目描述 输入一棵二叉搜索树，将该二叉搜索树转换成一个排序的循环双向链表。要求不能创建任何新的节点，只能调整树中节点指针的指向。 为了让您更好地理解问题，以下面的二叉搜索树为例： 我们希望将这个二叉搜索树转化为双向循环链表。链表中的每个节点都有一个前驱和后继指针。对于双向 ...
