怎样由遍历序列确定二叉树

在文 [1 ]至文 [4]中都介绍了遍历一棵二叉树的三种方法 :先序遍历、中序遍历和后序遍历 .每棵二叉树的先序遍历序列、中序遍历序列和后序遍历序列都是唯一的 .但是不同的二叉树的先序遍历序列或中序遍历序列或后序遍历序列有可能是相同的 .就如我们已知一个关系要求能求出它的关系矩阵 ,已知一个关系的关系矩阵也能求出关系矩阵所表示的关系一样 ,要求我们不但能从二叉树求它的遍序序列 ,而且能从二叉树的遍历序列求出它们所表示的二叉树 .在文 [1 ]中只指出 :给定结点的先序序列和中序序列可唯一确定一棵二叉树 .但文 [1 ]没有给出证明 .本文指出了由后序遍历序列和中序遍历序列也可唯一确定一棵二叉树 ,并给出了相应的证明

High-School Students' Attitudes Regarding Procedural Abstraction

During the last decade a new computer science curriculum has been taught in Israeli high schools. This curriculum introduces CS concepts and problem-solving methods independently of specific computers and programming languages, along with the practical implementation of those concepts and methods encountered in actual programming languages. The advanced study unit of the curriculum, Software Design, introduces the students to various aspects of software systems design through the use of abstract data types (ADTs). One main goal of the unit is to develop abstract thinking skills and problem-solving abilities. More specifically, the unit presents principles such as procedural abstraction, data abstraction, information hiding, modularity, efficiency, and reuse of code.We present the results of a preliminary study whose aim was to assess students' attitudes regarding procedural abstraction. The research population consisted of high-school students who attended the Software Design course (beginners), and a control group of undergraduate CS students (advanced). The results of the study clearly indicated a significant difference between the attitudes of the two groups. We found that the advanced students preferred algorithms that were formulated to some extent with high-level abstraction; however, they encountered a cognitive barrier when dealing with algorithms that they had evaluated as too abstract for them. However, beginners felt more comfortable with algorithms with low-level abstraction. Nevertheless they showed open-mindedness toward some degree of procedural abstraction. The results of the study were used to design scaffolding problem-solving tools for algorithm development, utilizing procedural abstraction techniques that can be adapted to various student populations (Haberman, B. (2002) SIGCSE Bulletin, 34(4), 60–64).
