How can you detect a cycle in a linked list?
- Breadth-First Search (BFS)
- Depth-First Search (DFS)
- Floyd's Tortoise and Hare Algorithm
- Linear Search
You can detect a cycle in a linked list using Floyd's Tortoise and Hare Algorithm. This algorithm uses two pointers moving at different speeds to traverse the list. If there's a cycle, the two pointers will eventually meet. It's an efficient O(n) algorithm for cycle detection.
