说明：  平衡二叉树生成 输入任意个节点 如 2 6 8 0为显示 可自动生成平衡二叉树 bf为平衡因子 h给深度 可插入删除 计算转动次数（wangliwei007也是我，质料没添全就换这个好号，请斑竹给我发个号好吗？我也想下载东西，急）
(balanced binary tree generating arbitrary input nodes as 2 6 8 0 to demonstrate that automatically generates balanced binary tree bf for the balance factor to the depth h can be inserted delete calculated rotational frequency (wangliwei007 me, not Tim material on the whole good for this, please give me a 62-000, okay? I would also like to download something radical))
