数据结构教学：chapter6——树的基本概念和节点操作

The chapter 6 of the data structure teaching courseware discusses General Trees, which are a finite set of one or more nodes with a designated root node. The remaining nodes are partitioned into disjoint subsets that are also trees, with each subset having its own root that is a child of the main root node. The General Tree Node is defined as an abstract data type (ADT) with template class Elem. It includes methods for creating, updating, and accessing tree nodes. The ADT allows for the manipulation of trees with arbitrary branching factors, providing a flexible and efficient data structure for various applications. This chapter covers the implementation and use of General Trees in programming and problem-solving, demonstrating their importance in organizing and managing complex hierarchical data structures.
