假设有棵树,长下面这个样子,它的前序遍历,中序遍历,后续遍历都很容易知道。
PreOrder: GDAFEMHZ
InOrder: ADEFGHMZ
PostOrder: AEFDHZMG
现在,假设仅仅知道前序和中序遍历,如何求后序遍历呢?比如,已知一棵树的前序遍历是”GDAFEMHZ”,而中序遍历是”ADEFGHMZ”应该...

原题如下;
Given inorder and postorder traversal of a tree, construct the binary tree.
Note:
You may assume that duplicates do not exist in the tree.
题意很简单:根据中序遍历和后序遍历的序列生成树
思路很简单:根据后序遍历的序列确定根节点,在中序遍历中找到根节点,将原来的序列分为左右两个部分,递归解决左右两个部分就可以解决这个问题。
Java代码如下:
publ...
