原题地址:http://oj.leetcode.com/problems/binary-tree-inorder-traversal/ 题意:二叉树的中序遍历。这道题用递归比较简单,考察的是非递归实现二叉树中序遍历。中序遍历顺序为:左子树,根,右子树。如此递归下去。 解题思路:假设树为: 1 / \ ...
Given a binary tree, return theinordertraversal of its nodes values. For example:Given binary tree , , , , 非递归版本: 用一个栈来模拟递归的情况, 首先思考inorder traverse的递归函数 traverse left tree visit current node traverse ...

题目: Given a binary tree, return the inorder traversal of its nodes' values. For example: Given binary tree {1,#,2,3}, return [1,3,2]. Note ...
从前序中序遍历来重构二叉树 经典题,从期末考试到考研什么的应该都有 前序遍历第一个肯定是root 在inorder里面去找root 左边的是leftsubtree , 右边的是rightsubtree 然后preorder除去order,后面lifetsubtree.size ...
原题地址:http://oj.leetcode.com/problems/construct-binary-tree-from-inorder-and-postorder-traversal/ 题意:根据二叉树的中序遍历和后序遍历恢复二叉树。 解题思路:看到树首先想到要用递归来解题。以这道题为 ...
