二叉树的创建及遍历实验

数据元素类型ElemType取float。

从键盘按照前序遍历的顺序依次输入二叉树的各元素，创建此二叉树。

非递归的方法输出该二叉树的中序遍历序列。

求该二叉树中大于x的结点个数。

-Binary tree creation and traversal experiment

Data elements the type ElemType take a float.

Input from the keyboard in accordance with the pre-order traversal order is in turn the various elements of the binary tree, to create this binary tree.

Non-recursive method to output the binary tree in preorder traversal sequence.

Find the number of nodes in the binary tree greater than x.
