A self-referential data structure, also known as a recursive data structure, is a data structure in which each instance of the structure contains a reference to another instance of the same type. This self-referential property allows for the creation of complex and hierarchical structures. Common examples of self-referential data structures include linked lists, trees, and graphs. Let's look at some common examples: 1. Linked List: In a linked list, each node contains data and a reference (or a pointer) to the next node in the sequence. The last node typically has a reference set to NULL to indicate the end of the list. struct Node { int data; struct Node* next; }; The next field is a self-reference to another Node structure. 2. Binary Tree: In a binary tree, each node has at most two children, each of which is a node in the same type. Nodes are connected through left and right pointers. struct TreeNode { int data; struct TreeNode*...
