+ * @brief
+ * [XOR List](https://en.wikipedia.org/wiki/XOR_linked_list) combines the properties of a 
+ * circular doubly linked list and XOR pointers to save memory and enhance performance. 
+ * Each node contains an XOR of the addresses of the previous and next nodes.
+ *
+ * In this implementation, functions to insert at the head, delete the first node, display list, get
+ * list size, and get element at index functions are coded.
