说明：  创建一个二叉树，对这棵动态二叉树进行分析，将其用静态二叉链表表示。二叉树的动态二叉链表结构中的每个结点有三个字段：data，lchild，rchild。静态二叉链表是用数组作为存储空间，每个数组元素存储二叉树的一个结点，也有三个字段：data，lchild，rchild。lchild和rdhild分别用于存储左右孩子的下标。
(Create a binary tree, analyze the dynamic binary tree, and express it with a static binary list. Each node in the dynamic binary list structure of a binary tree has three fields: data, lchild, rchild. Static binary list uses arrays as storage space. Each element of the array stores a node of the binary tree. There are also three fields: data, lchild, rchild. Lchild and rdhild are used to store the subscriptions of left and right children respectively.)
