03-树3. Tree Traversals Again (25) 题目来源:http://www.patest.cn/contests/mooc-ds/03-%E6%A0%913 An inorder binary tree traversal can be implemented in a non-recursive way with a stack. For example, suppose that when a 6-node binary tree (with the keys num…
7-4 Cartesian Tree (30分) A Cartesian tree is a binary tree constructed from a sequence of distinct numbers. The tree is heap-ordered, and an inorder traversal returns the original sequence. For example, given the sequence { 8, 15, 3, 4, 1, 5, 12, 1…
1020 Tree Traversals Suppose that all the keys in a binary tree are distinct positive integers. Given the postorder and inorder traversal sequences, you are supposed to output the level order traversal sequence of the corresponding binary tree. Input…
好不容易又到周五了,周末终于可以休息休息了.写这一篇随笔只是心血来潮,下午问了一位朋友PAT考的如何,顺便看一下他考的试题,里面有最后一道题,是关于给出中序遍历和后序遍历然后求一个层次遍历.等等,我找一下链接出来...... 1127. ZigZagging on a Tree (30):https://www.patest.cn/contests/pat-a-practise/1127 突然想起以前学数据结构的时候如果给出一个中序遍历和一个后序遍历然后让你画出树的结构或求出先序遍历之类的题目,…
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 给定一个二叉树,返回他的中序遍历的节点的values. 例如: 给定一个二叉树 {1,#,2,3}, 1 \ 2 / 3 返回 [1,3,2]. 笔记: 递归解决方案是微不足道的,你可以用迭代的方法吗? 困惑什么"{1,#,2,3}" 的意思吗? > read more on how binary tree is s…
