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 ...
One way to serialize a binary tree is to use pre-order traversal. When we encounter a non-null node, we record the node's value. If it is a null ...
题目：验证二叉搜索树 难度：Medium 题目内容： Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows ...
Given a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node ...
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. ...
binary tree is defined as a binary tree in which t ...
二叉搜索树 若既要求对象集合的组成可以高效率的动态调整，同时也要求能够高效率的查找。 通过对二分查找策略的抽象与推广，定义并实现二叉搜索树结构，基于半线性的树形结构，正是后续内容的立足点和出发点。 二叉搜索树为我们同时实现高效的静态操作以及动态操作提供了基础 ...
