Key Concepts

Data Structure

A data structure is a way of organizing and storing data so that it can be used efficiently. It serves as the backbone for managing and accessing data in programming, with examples ranging from arrays and lists to trees and graphs.

Self-reference

Self-reference is a concept where an entity refers to itself, either directly or indirectly. In the context of data structures, it means that a structure includes a reference or pointer to another instance of the same structure, enabling the creation of complex, interconnected systems.

Recursive Data Structure

A recursive data structure is one that is defined in terms of a smaller instance of itself. Self-referential data structures are inherently recursive because they contain elements that are similar in nature to the overall structure, which allows operations like traversal and manipulation to be performed recursively.
