说明：  随机生成用户要求个数的整数，生成二叉树（无重复）， 可以进行生成、遍历、查找二叉树，而且进行动态的查找， 如果没有找到节点就把这个值接到树上 能够显示节点的产生顺序、平衡因子（失败），节点值
(Randomly generated integer number of user requirements to generate binary tree (without repetition), can be generated, ergodic, binary tree search, and dynamically find, if they did not find this value from the node tree to display nodes have the order, balance factor (failure), the node value)
