题目Given a binary search tree (BST), find the lowest common ancestor (LCA) of two given nodes in the BST.思路题目要求一个二叉排序树的两个节点的公共父节点,说通俗点,其实就是这两个节点所在的分支是从哪里开始分叉的。求出这个分叉点。对于二叉排序树,它的一个特点就是:一个节点的左子树节点都小于该节点,而...

题目Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree.思路这一次说的是一个普通的二叉树,给出两个节点,求他们的最低公共父节点。
回想一下,当这棵二叉树是二分查找树的时候的解决方案:
