[LeetCode] 98. Validate Binary Search Tree(是否是二叉搜索树) ☆☆☆

描述 解析 二叉搜索树,其实就是节点n的左孩子所在的树,每个节点都小于节点n. 节点n的右孩子所在的树,每个节点都大于节点n. 定义子树的最大最小值 比如:左孩子要小于父节点:左孩子n的右孩子要大于n的父节点.以此类推. 中序遍历 中序遍历时,输出的值,和前一个值比较,如果大,就失败. 代码 /** * Definition for a binary tree node. * public class TreeNode { * int val; * TreeNode left; * TreeNo…
