输入字符，建立平衡二叉树，再输出字符，中序，抛砖引玉-input characters, the establishment of balanced binary tree, and the output of characters, sequence, something

用二叉链表做存储结构，输入键值序列，建立一棵二叉排序树并在二叉排序树上实现查找算法。-To do with binary storage structure list, enter the key sequence, set up a binary sort tree and binary search algorithm to sort the tree implementation.

linux下的源码，关于二叉树的建立，添加，删除，销毁
