A singly circular linked list is a data structure that consists of a sequence of nodes, where each node contains data and a reference (or pointer) to the next node in the sequence. Unlike a standard linked list, the last node in a singly circular linked list points back to the first node, creating a circular structure. This allows for continuous traversal of the list without needing to start over at the head. In a singly circular linked list, you can easily add or remove nodes without shifting other elements, making it efficient for dynamic data management. Operations such as insertion, deletion, and traversal can be performed in constant time, depending on the position of the node. This structure is useful in applications like round-robin scheduling and buffer management.
