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, generate a binary tree (no duplicates), can be generated, traverse Find a binary tree, and dynamic lookup If you did not find the node received a tree to be able to put the value of the order in which the nodes generate balance factor (failure), the value of a node
