Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST. According to the definition of LCA on Wikipedia: “The lowest common ancestor is defined between two nodes p and q as the lowest node in T that has…
235. 二叉搜索树的最近公共祖先 235. Lowest Common Ancestor of a Binary Search Tree 题目描述 给定一个二叉搜索树,找到该树中两个指定节点的最近公共祖先. 百度百科中最近公共祖先的定义为: "对于有根树 T 的两个结点 p.q,最近公共祖先表示为一个结点 x,满足 x 是 p.q 的祖先且 x 的深度尽可能大(一个节点也可以是它自己的祖先)." 例如,给定如下二叉搜索树: root = [6,2,8,0,4,7,9,null,nul…
