下列关于二叉树遍历的说法正确的有: Which sentences of the followings are right about traversal of a binary tree:

A、前序和中序遍历的顺序恰好一样的二叉树,只能是空二叉树或者独根二叉树这两种情况。Only the sequences of preorder and infix order of the binary tree with no nodes or only one node are the same.

B、所有结点左子树为空的二叉树的前序和中序遍历顺序恰好一样。The sequences of preorder and infix order of a binary tree with all nodes without left child tree are the same.

C、所有结点右子树为空的二叉树的前序和中序遍历顺序恰好一样。The sequences of preorder and infix order of a binary tree with all nodes without right child tree are the same.

D、只有空二叉树和一个根结点的二叉树这两种二叉树的前序和后序遍历的顺序恰好一样。Only the sequences of preorder and post order of the binary tree with no nodes or only one node are the same.

E、所有结点左子树为空的二叉树的前序和后序遍历顺序恰好一样。The sequences of preorder and post order of a binary tree with all nodes without left child tree are the same.

F、所有结点右子树为空的二叉树的前序和后序遍历顺序恰好一样。The sequences of preorder and post order of a binary tree with all nodes without left child tree are the same.

G、只有空二叉树和一个根结点的二叉树这两种二叉树的中序和后序遍历的顺序恰好一样。Only the sequences of infix order and post order of the binary tree with no nodes or only one node are the same.

H、所有结点左子树为空的二叉树的中序和后序遍历顺序恰好一样。The sequences of infix order and post order of a binary tree with all nodes without left child tree are the same.

I、所有结点右子树为空的二叉树的中序和后序遍历顺序恰好一样。The sequences of infix order and post order of a binary tree with all nodes without right child tree are the same.

J、存在一棵非空二叉树,它的前序、中序和后序遍历都是一样的。There exists a binary tree with at least one node, whose preorder, infix order and post order are all the same.

第6题

从空二叉树开始,严格按照二叉搜索树的插入算法(不进行旋转平衡),逐个插入关键码{18,73,10,5,68,9
9,27,41,51,32,25}构造出一棵二叉搜索树,对该二叉搜索树按照前序遍历得到的序列为?(答案中每两个元素之间用一个空格隔开) From a null binary tree, insert key values {18, 73, 10, 5, 68, 99, 27, 41, 51, 32, 25} successively according to the insertion algorithm of a binary search tree strictly (no rotation and balance) to construct a binary search tree. Please write down the sequence of preorder of this binary search tree. (There is one blank space between two elements)
