Understanding Circular Linked Lists

A circular linked list is a type of linked list where the last node of the list points back to the first node, creating a loop. In other words, the next pointer of the last node points to the head of the list instead of being nullptr. The circular arrangement allows for continuous traversal, making operations like rotation and constant-time insertions and deletions at both ends more efficient.

Key Features of Circular Linked Lists:

1. Circular Structure:
   * The last node's next pointer points back to the head node, forming a closed loop.
2. No Null Pointers:
   * Unlike traditional linked lists, there are no nullptr pointers in a circular linked list.
3. Efficient Traversal:
   * Traversal can be continuous, with the end of the list leading back to the beginning.
4. Dynamic Size:
   * Circular linked list can dynamically adjust their size during insertions and deletions.
