１本程序在vc++6.0编译通过并能正常运行。
２主界面程序已经尽量做到操作简便了，用户只需要根据提示一步步进行操作就行了。
六思考和总结：这个课程设计的各个基本操作大部分都在我的综合性实验中实现了，所以做这个主要攻克插入和删除这两个算法！其中插入在书本上已经有了，其中的右平衡算法虽然没有给出，但通过给出的左平衡算法很容易就可以写出右平衡算法。
所以最终的点就在于删除算法的实现！做的过程中对插入算法进行了非常非常多次的尝试！花了非常多的时间，这其中很多时候是在对程序进行单步调试，运用了ＶＣ６。
０的众多良好工具，也学到了很多它的许多好的调试手段。
其中删除算法中最难想到的一点是：在用叶子结点代替要删除的非叶子结点后，应该递归的运用删除算法去删除叶子结点！这就是整个算法的核心，其中很强烈得体会到的递归的强大，递归的最高境界（我暂时能看到的境界）！其它的都没什么了。
选做的那两个算法很容易实现的：１合并两棵平衡二叉排序树：只需遍历其中的一棵，将它的每一个元素插入到另一棵即可。
２拆分两棵平衡二叉排序树：只需以根结点为中心，左子树独立为一棵，右子树独立为一棵，最后将根插入到左子树或右子树即可。
BSTreeEmpty(BSTreeT)初始条件：平衡二叉排序树存在。
操作结果：若T为空平衡二叉排序树，则返回TRUE,否则FALSE.BSTreeDepth(BSTreeT)初始条件：平衡二叉排序树存在。
操作结果：返回T的深度。
LeafNum(BSTreeT)求叶子结点数，非递归中序遍历NodeNum(BSTreeT)求结点数，非递归中序遍历DestoryBSTree(BSTree*T)后序遍历销毁平衡二叉排序树TR_Rotate(BSTree*p)对以*p为根的平衡二叉排序树作右旋处理，处理之后p指向新的树根结点即旋转处理之前的左子树的根结点L_Rotate(BSTree*p)对以*p为根的平衡二叉排序树作左旋处理，处理之后p指向新的树根结点，即旋转处理之前的右子树的根结点LeftBalance(BSTree*T)对以指针Ｔ所指结点为根的平衡二叉排序树作左平衡旋转处理，本算法结束时，指针Ｔ指向新的根结点RightBalance(BSTree*T)对以指针Ｔ所指结点为根的平衡二叉排序树作右平衡旋转处理，本算法结束时，指针Ｔ指向新的根结点Insert_AVL(BSTree*T,TElemTypee,int*taller)若在平衡的二叉排序树Ｔ中不存在和e有相同的关键字的结点，则插入一个数据元素为e的新结点，并返回OK,否则返回ERROR.若因插入而使二叉排序树失去平衡，则作平衡旋转处理布尔变量taller反映Ｔ长高与否InOrderTraverse(BSTreeT)递归中序遍历输出平衡二叉排序树SearchBST(BSTreeT,TElemTypee,BSTree*f,BSTree*p)在根指针Ｔ所指的平衡二叉排序树中递归的查找其元素值等于e的数据元素，若查找成功，则指针p指向该数据元素结点，并返回TRUE，否则指针p指向查找路径上访问的最后一个结点并返回FALSE，指针f指向Ｔ的双亲，其初始调用值为NULLDelete_AVL(BSTree*T,TElemTypee,int*shorter)在平衡二叉排序树中删除元素值为e的结点,成功返回OK,失败返回ERRORPrintBSTree_GList(BSTreeT)以广义表形式打印出来PrintBSTree_AoList(BSTreeT,intlength)以凹入表形式打印,length初始值为0Combine_Two_AVL(BSTree*T1,BSTreeT2)合并两棵平衡二叉排序树Split_AVL(BSTreeT,BSTree*T1,BSTree*T2)拆分两棵平衡二叉树}(2)存储结构的定义：typedefstructBSTNode{ TElemTypedata; intbf;//结点的平衡因子 structBSTNode*lchild,*rchild;//左.右孩子指针}BSTNode,*BSTree;

本次实验采用C编写，将内存空间定义为结构体链表，成员有作业名name[20]、作业首址s_add、作业长度length及下一节点的指针next；
空闲分区表定义为结构体数组，成员有空闲区首址s_add、空闲区长度length、表项状态state。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
