Non-Linear Data Structures

Non-linear data structures form a crucial class of data structures with extensive applications in designing efficient algorithms. Unlike linear data structures, such as arrays and linked lists, non-linear structures allow data elements to be stored and accessed in a more complex, hierarchical manner. These structures enable the efficient handling of relationships, dependencies, and hierarchical data, making them vital for solving a wide range of computational problems.

In this chapter, we begin by exploring the general properties and characteristics that define non-linear data structures. Following this, we discuss two major groups: graphs and trees. Graphs are versatile structures used to model relationships between objects, while trees represent hierarchical relationships in a more structured form. Finally, we examine a special case of binary trees, known as heaps, which are essential for implementing efficient algorithms such as heapsort. Learning about...
