前端算法-二叉搜索树中第K小的元素

题目给定一个二叉搜索树的根节点 root ，和一个整数 k ，请你设计一个算法查找其中第 k 个最小元素（从 1 开始计数）。输入： root = [3,1,4,null,2], k = 1 输出： 1思路一我们先判断一下当前root形参是否为空，如果为空则直接返回null,接下来在...

【前端算法】求二叉搜索树第k小值

二叉树（Binary Tree）是一颗树每个节点，最多只能有2个子节点树节点的数据结构{ value，left？，right？}二叉树的遍历前序遍历：root -> left -> right (根左右)中序遍历：left -> root -> right (左根右)后序遍历...
