二叉树的构建掌握基于先序遍历构造二叉链表的算法-Construction of binary tree

该程序是实现双亲表的算法，主要用于二叉树的应用-The procedure is the algorithm of the parent table, mainly used for the application of the binary tree

常用的算法经典代码，包括快速排序，冒泡排序等各种排序方法，还有二叉树的前序、中序和后序遍历等-The classic algorithm code, including quick sort and bubble sort sorting methods, as well as the preamble of the binary tree, inorder and postorder traversal, etc.

非递归中序遍历二叉树：要求从键盘输入二叉树各结点的值，并使用二叉链表来存储二叉树；使用非递归算法遍历二叉树，在屏幕上打印出二叉树中序遍历序列。-Non-recursive traversal of binary tree: the input binary tree node value from the keyboard and use the binary tree to store binary tree non-recursive algorithm for binary tree t
