建立与遍历一棵二叉树历来为数据结构中不可缺少的内容。由于C语言仅有单向的“值传递”，所以多年来数据结构教课书中，皆使用指针函数来编程，进而增加了教师在讲述中的复杂性。构造一个用递归函数建立二叉树的C语言程序，可以解决多年来C语言教课书中没有解决的问题。 相似文献

C语言有较丰富的数据类型、运算符以及函数,能直接与内存打交道,使修改、编辑其他程序与文档变得简单。树型结构是一类重要的非线性数据结构,其中以树和二叉树最为常用。二叉树的遍历算法是树形结构中其他运算的基础,在二叉树遍历的各种算法中包括了一些精致的、并且在其他应用范围内也有用的技巧,所以本文主要讨论用C语言去实现二叉树遍历的几种不同算法。 相似文献

二叉树是数据结构中的一种重要的数据结构类型,因其非顺序的结构和多种遍历方法,再加上栈和队列的运用,递归和非递归算法的不同的语言描述,使其在遍历算法中显得非常复杂。本文就这一问题进行了简单浅显的探讨。 相似文献

随着关系数据库技术的应用越来越广泛,利用关系表格、关系代数、结构化查询语言等研究基于外存储结构的数据结构有着实际的意义。本文从一个具有树结构的学校管理模型出发,提出一种用关系数据库表来表示树的方法,讨论了如何利用关系代数和SQL语言对表格进行一般查询,借助JaVa语言实现二叉树中比较典型的前序、中序和后序算法,最后对文章开始引出的问题给出了实现程序。 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help? 相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love. 相似文献

The problem on the geometrc inequalities involving an n-dimensional simplex and its inscribed simplex is studied. Aninequality is established, which reveals that the difference between the squared circumradius of the n-dimensional simplex andthe squared distance between its circumcenter and barycenter times the squared circumradius of its inscribed simplex is not lessthan the 2(n-1)th power of n times its squared inradius, and is equal to when the simplex is regular and its inscribed siplex is atangent point one. Deduction from this inequality reaches a generalization of n-dimensional Euler inequality indicating that thecircumradius of the simplex is not less than the n-fold inradius. Another inequality is derived to present the relationship betweenthe circumradius of the n-dimensional simplex and the circumradius and inradius of its pedal simplex. 相似文献

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject. 相似文献

Using virtual reality for interactive design gives a designer an intuitive vision of a design and allows the designer to achieve a viable, optimal solution in a timely manner. The article discusses the process of making the Virtual Reality System of the Humble Administrator＇s Garden. Translating building data to the Virtual Reality Modeling Language （VRML） is by far unsatisfactory. This creates a challenge for computer designers to do optimization to meet requirements. Five different approaches to optimize models have been presented in this paper. The other methods are to optimize VRML and to reduce the file size. This is done by keeping polygon counts to a minimum and by applying such techniques as object culling and level-ofdetail switching. 相似文献
