废话不多说，喊一句号子鼓励自己：程序员永不失业，程序员走向架构！本篇Blog的主题是【二叉树的节点查找】，使用【二叉树】这个基本的数据结构来实现，这个高频题的站点是：CodeTop，筛选条件为：目标公司+最近一年+出现频率排序，由高到低的去牛...

代码随想录算法训练营第二十天 | LeetCode 530. 二叉搜索树的最小绝对差、501. 二叉搜索树中的众数、236. 二叉树的最近公共祖先

1. LeetCode 530. 二叉搜索树的最小绝对差1.1 思路因为是二叉搜索树，按照中序遍历是一个有序序列，此时相邻的两个节点的值就是最小绝对差我们用双指针，一个指向前面pre一个紧跟后面root，用result记录root.val-pre.val的差的最小值。result和pre记录为全局变...

算法训练Day21|530.二叉搜索树的最小绝对差 ● 501.二叉搜索树中的众数 ● 236. 二叉树的最近公共祖先

LeetCode:530.二叉搜索树的最小绝对差530. 二叉搜索树的最小绝对差 - 力扣（LeetCode）1.思路利用二叉搜索树的典型特性：中序遍历输出是一个升序的数组。在此基础之上结合双指针法可以直接在二叉搜索树上直接进行中序遍历获取最小绝对值差ans。2. 代码实现 1class Solut...
