Explanation: Memory efficient doubly linked list has only one pointer to traverse the list back and forth. The implementation is based on pointer difference. It uses bitwise XOR operator to store the front and rear pointer addresses. Instead of storing actual memory address, every node store the XOR address of previous and next nodes.

Head node is known in circular linked list
Explanation:
In a normal linked list, the ‘next’ pointer of the last node points to null. However, in a circular linked list, the ‘next’ pointer of the last node points to the head (first element) of the list. Every node in a circular linked list can be a starting point(head).
