本程序是一个用树常用算法，信号…

代码说明：

本程序是实现二叉树跟树的常用算法，都是尽量用非递归来编写的。关于二叉树的都可以从键盘动态输入，关于树的就不可以，原因是树的结构问题，在程序中，树的建立用到动态左孩子/右孩子建立-this program is a binary tree with the tree is commonly used algorithm, as possible, to use non- recursive prepared. On the binary tree can be dynamic input from the keyboard, on the tree will not be able to because of the tree structure, in the process, the tree is used to establish dynamic children left/right to establish child
