简单介绍了一种数据结构的构建及其使用情况,-introduces a simple data structure of the building and its use,

主要是二叉树的一些性质的操作。包括复制，清空，求取树高，树中元素的个数，得到根结点，父亲结点，所有祖先，左儿子，右儿子，插入左儿子，右儿子，查找某个元素，以及前、中、后、层次遍历和相关的操作。另外，可以树形显示这棵树的信息。-Some properties are mainly binary operation. Including reproduction, empty, to strike a tree height, the number of elements in the tree get root node, the father node, all the ancestors, the left son, right son, insert the left son, right son, to find an element, and the former , during and after, hierarchical traversal and related operations. In addition, you can display tree tree information.
