消除递归不一定需要使用栈。 答案:正确 在开散列表中不会出现堆积现象。 答案:正确 在链栈上进行进栈操作时，不需判断栈满。 答案:正确 算法的正确性，一般不进行形式化的证明，而是用测试来验证。 答案:正确 顺序表不需存放指针，链表要存放指针，故链表的存储空间要求总是比顺序表大。 答案:错误 如果n个顶点的无向图有n条边，则图中肯定有回路。 答案:正确 图G的生成树T是G的子图。 答案:正确 数组的基本运算有读、写、插入、删除等。 答案:错误 不管树的深度和形态如何，也不可能构造出一棵有100个结点的哈夫曼树。 答案:正确 如果根结点的左子树和右子树高度差不超过1，则该二叉树是平衡二叉树。 答案:错误 排序的目的是为了方便以后的查找。 答案:正确 以中序方式遍历一个堆，则得到一个有序序列。 答案:正确 二叉树中可能所有结点的度都小于2。 答案:正确 顺序表可以按序号随机存取。 答案:正确 在二叉排序树中，即使删除一个结点后马上再插入该结点，该二叉排序树的形态也可能不同。答案:正确 队列在使用中必须设置两个指针，分别指向真正的队头和队尾的位置。 答案:错误 数据的逻辑结构和运算集组成问题的数学模型，与计算机无关。
对称矩阵压缩存储后仍然可以随机存取。 答案:正确 有向图中顶点i的出度等于邻接矩阵中第i行中1的个数；入度等于第i列中1的个数。 答案:错误 树和森林都可转化为二叉树，故对给定的二叉树，不能区分是由树还是森林转换来的。 答案:错误 循环队列中入队和出队的节点位置可出现在数组的任一端，已不满足“一端进另一端出”的要求，故实际上已不是队列了。 答案:错误 顺序查找法不仅可用于顺序表上的查找，也可用于链表上的查找。 答案:正确 有向图中边数等于邻接矩阵中1的个数；也等于邻接表中的边表结点数。 答案:正确 直接插入排序是稳定的，而Shell排序就是调用若干趟直接插入排序，故也是稳定的。 答案:错误 基数排序不需进行关键字间的比较，故执行时间比基于比较的排序方法要快。 答案:错误 由二叉树的先根和后根序列可以唯一确定该二叉树。 答案:错误 不论数据如何组织，分别在10000个结点和10个结点的查找表中进行查找，前者的平均查找长度肯定比后者大。 答案:错误 在线索二叉树上，求结点的(遍历)前趋和后继时可利用线索得到，即不必进行遍历了。 答案:错误 单链表中取第i个元素的时间与i成正比。 答案:正确 广义表不仅是线性表的推广，也是树的推广。 答案:正确 拓扑排序可以分析某工程能否顺利进行。 答案:正确 哈夫曼树中不存在度为1的结点。 答案:正确 在数据结构中，算法的空间耗费包括代码和数据两部分。
