106. 从中序与后序遍历序列构造二叉树 - 给定两个整数数组 inorder 和 postorder ,其中 inorder 是二叉树的中序遍历, postorder 是同一棵树的后序遍历,请你构造并返回这颗 二叉树 。 示例 1: [https://assets.leetcode.com/uploads/2021/02/19/tree.jpg] 输入:in
Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 解题思路: 这道题和上一题Construct Binary Tree from Preorder and Inorder Traversal就很像了。
