please refer to my previous post:Lowest Common Ancestor of a Binary Search Tree (BST)or the definition of LCAhere. Using the tree above as an example, the LCA of nodes5and1is3. Please note that LCA for nodes5and4is5.

Given two binary trees original and cloned and given a reference to a node target in the original tree. The cloned tree is a copy of the original tree. Return a reference to the same node in the cloned tree. Note that you are not allowed to change any of the two trees or the target...

这道题实际上考察的是一种叫线索二叉树的数据结构,而构造这种树的方法称之为Morris遍历法,在我之前的博客Binary Tree Inorder Traversal 二叉树的中序遍历有详细的介绍,然而并没什么卵用,因为这道题给了个条件,说每个节点都可以链接到其父节点,这样一来就大大的简化了问题。首先我们知道二叉搜索树的性质的左<=根...
