Data Structures Questions
The concept of a circular linked list is a variation of a linked list where the last node of the list points back to the first node, creating a circular structure. This means that there is no null or empty node at the end of the list, and traversal can be done indefinitely in a loop. The circular linked list can be singly or doubly linked, with each node containing a reference to the next node in the sequence. This data structure is useful in scenarios where continuous traversal or rotation is required, such as in scheduling algorithms or circular buffers.
