Q3. Explain how to detect a cycle in a linked list.
Ans. 
Use Floyd's Tortoise and Hare algorithm to detect a cycle in a linked list.
• Start with two pointers, slow and fast, moving at different speeds.

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

• If there is no cycle, the fast pointer will reach the end of the list.

• Example: 1->2->3->4->5->2 (cycle at node 2), slow and fast pointers will meet at node 2.
