Ans. 
Detect if a singly linked list forms a cycle by checking if a node's next pointer points back to a previous node.
• Use Floyd's Tortoise and Hare algorithm to detect a cycle in the linked list.

• Maintain two pointers, one moving at twice the speed of the other.

• If there is a cycle, the two pointers will eventually meet.

• If one of the pointers reaches the end of the list (null), there is no cycle.
