[LeetCode] 889. Construct Binary Tree from Preorder and Postorder Traversal 由先序和后序遍历建立二叉树

Return any binary tree that matches the given preorder and postorder traversals.

Values in the traversals?pre?and?post?are distinct?positive integers.

Example 1:

Input: pre = [1,2,4,5,3,6,7], post = [4,5,2,6,7,3,1]
Output: [1,2,3,4,5,6,7]

Note:

  • 1 <= pre.length == post.length <= 30
  • pre[]?and?post[]?are both permutations of?1, 2, ..., pre.length.
  • It is guaranteed an answer exists. If there exists multiple answers, you can return any of them.

leetcode题解:Construct Binary Tree from Preorder and Inorder Traversal (根据前序和中序遍历构造二叉树)

题目: Given preorder and inorder traversal of a tree, construct the binary tree. Note:You may assume that duplicates do not exist in the tree. 说明: 1)二叉树可空 2)思路:a.根据前序遍历的特点, 知前序序列(PreSequence)的首个元素(PreSequence[0])为二叉树的根(root),  然后在中序序列(InSequence)中查找此根(

【leetcode】Construct Binary Tree from Preorder and Inorder Traversal

问题: 给定二叉树的前序和中序遍历,重构这课二叉树. 分析: 前序.中序.后序都是针对于根结点而言,所以又叫作先根.中根.后根(当然不是高跟). 前序:根  左 右 中序:左  根 右 对二叉树,我们将其进行投影,就会发现个有趣的事: 发现投影后的顺序,恰好是中序遍历的顺序,这也就是为什么在构造二叉树的时候,一定需要知道中序遍历,因为中序遍历决定了结点间的相对左右位置关系.所以,对一串有序的数组,我们可以来构建二叉有序数,并通过中序遍历,就可以得到这个有序的数组. 既然中序遍历可以通过根结点将序

[LeetCode]*105.Construct Binary Tree from Preorder and Inorder Traversal

题目 Given preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 思路 主要是根据前序遍历和中序遍历的特点解决这个题目. 1.确定树的根节点.树根是当前树中所有元素在前序遍历中最先出现的元素. 2.求解树的子树.找出根节点在中序遍历中的位置,根左边的所有元素就是左子树,根右边的所有元
