第二章部分习题参考答案

2 何时选用顺序表,何时选用链表作为线性表的存储结构合适? 各自的主要优缺点是什么? 在实际应用中,应根据具体问题的要求和性质来选择顺序表或链表作为线性表的存储结构,通常有以下几方面的考虑: 1. 基于空间的考虑。当要求存储的线性表长度变化不大,易于事先确定其大小时,为了节约存储空间,宜采用顺序表;反之,当线性表长度变化大,难以估计其存储规模时,采用动态链表作为存储结构为好。 2. 基于时间的考虑。若线性表的操作主要是进行查找,很少做插入和删除操作时,采用顺序表做存储结构为宜;反之,若需要对线性表进行频繁地插入或删除等的操作时,宜采用链表做存储结构。并且,若链表的插入和删除主要发生在表的首尾两端,则采用尾指针表示的单循环链表为宜。 顺序表的主要优点: 没使用指针,不用花费附加开销; 线性表元素的读写访问非常简洁便利 链表的主要优点:无需事先了解线性表的长度; 能够适应经常插入删除内部元素的情况; 允许线性表的长度有很大变化 3 在顺序表中插入和删除一个结点平均需要移动多少个结点? 具体的移动次数取决于哪两个因素? 在等概率情况下,顺序表中插入一个结点需平均移动n/2 个结点。删除一个结点需平均移动(n-1)/2个结点。具体的移动次数取决于顺序表的长度n以及需插入或删除的位置i °i 越接近n 则所需移动的结点数越少。 4 链表所表示的元素是否有序? 如有序,则有序性体现于何处? 链表所表示的元素是否一定要在物理上是相邻的? 顺序表的有序性又如何理解? 有序。有序性体现在通过指针数据元素有序的相连。物理上不一定要相邻。顺序表的有序不仅体现在逻辑结构上有序,而且在物理结构(储存结构)也有序。 5 设顺序表L是递增有序表,试写一算法,将x插入到L中并使L仍是递增有序表。因已知顺 序表L是递增有序表,所以只要从顺序表终端结点(设为i位置元素)开始向前 寻找到第一个小于或等于x的元素位置i后插入该位置即可。 在寻找过程中,由于大于x 的元素都应放在x 之后,所以可边寻找,边后移元素,当找到

《全新版大学英语综合教程1 课后翻译及答案》Unit 1 Growing Up 为自己而写 ——拉塞尔·贝克 从孩提时代,我还住在贝尔维尔时,我的脑子里就断断续续地转着当作家的念头,但直等到我高中三年级,这一想法才有了实现的可能。在这之前,我对所有跟英文课沾边的事都感到腻味。我觉得英文语法枯燥难懂。我痛恨那些长而乏味的段落写作,老师读着受累,我写着痛苦。弗利格尔先生接我们的高三英文课时,我就准备着在这门最最单调乏味的课上再熬上沉闷的一年。弗利格尔先生在学生中以其说话干巴和激励学生无术而出名。据说他拘谨刻板,完全落后于时代。我看他有六七十岁了,古板之极。他戴着古板的毫无装饰的眼镜,微微卷曲的头发剪得笔齐,梳得纹丝不乱。他身穿古板的套装,领带端端正正地顶着白衬衣的领扣。他长着古板的尖下巴,古板的直鼻梁,说起话来一本正经,字斟句酌,彬彬有礼,活脱脱一个滑稽的老古董。 我作好准备,打算在弗利格尔先生的班上一无所获地混上一年,不少日子过去了,还真不出所料。后半学期我们学写随笔小品文。弗利格尔先生发下一张家庭作业纸,出了不少题目供我们选择。像"暑假二三事"那样傻乎乎的题目倒是一个也没有,但绝大多数一样乏味。我把作文题带回家,一直没写,直到要交作业的前一天晚上。我躺在沙发上,最终不得不面对这一讨厌的功课,便从笔记本里抽出作文题目单粗粗一看。我的目光落在"吃意大利细面条的艺术"这个题目上。

这个题目在我脑海里唤起了一连串不同寻常的图像。贝尔维尔之夜的清晰的回忆如潮水一般涌来,当时,我们大家一起围坐在晚餐桌旁——艾伦舅舅、我母亲、查理舅舅、多丽丝、哈尔舅舅——帕特舅妈晚饭做的是意大利细面条。那时意大利细面条还是很少听说的异国食品。多丽丝和我都还从来没吃过,在座的大人也是经验不足,没有一个吃起来得心应手的。艾伦舅舅家诙谐有趣的场景全都重现在我的脑海中,我回想起来,当晚我们笑作一团,争论着该如何地把面条从盘子上送到嘴里才算合乎礼仪。 突然我就想描述那一切,描述当时那种温馨美好的气氛,但我把它写下来仅仅是想自得其乐,而不是为弗利格尔先生而写。那是我想重新捕捉并珍藏在心中的一个时刻。我想重温那个夜晚的愉快。然而,照我希望的那样去写,就会违反我在学校里学的正式作文的种种法则,弗利格尔先生也肯定会打它一个不及格。没关系。等我为自己写好了之后,我可以再为弗利格尔先生写点什么别的东西。 等我写完时已是半夜时分,再没时间为弗利格尔先生写一篇循规蹈矩、像模像样的文章了。第二天上午,我别无选择,只好把我为自己而写的贝尔维尔晚餐的故事交了上去。两天后弗利格尔先生发还批改过的作文,他把别人的都发了,就是没有我的。我正准备着遵命一放学就去弗利格尔先生那儿挨训,却看见他从桌上拿起我的作文,敲了敲桌子让大家注意听。 "好了,孩子们,"他说。"我要给你们念一篇小品文。文章的题目是: 吃意大利细面条的艺术。"
