Given inorder and postorder traversal of a tree, construct the binary tree.
Note:
You may assume that duplicates do not exist in the tree.
题目解析:
用中序遍历和后续遍历还原二叉树。并且二叉树的节点的值没有重复的。这样就好做了,我们知道后序遍历...

Given inorder and postorder traversal of a tree, construct the binary tree.
Note:
You may assume that duplicates do not exist in the tree.
思路:这题和上题类似,前序第一个是根节点,后序遍历最后一个是根节点。其余步骤类似。
代码如下:
/**
