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 ...

Given inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree ...

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 ...
