第1题:
第2题:
某二叉树的前序和中序遍历序列正好一样,则该二叉树中的任何结点一定都无左孩子。
第3题:
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 sam
