Cycle Detection (Floyd's Algorithm)
Also known as the 'tortoise and hare' algorithm, this elegant technique detects cycles in linked lists or sequences using O(1) space. Uses two pointers moving at different speeds—if there's a cycle, they will eventually meet. Essential for detecting infinite loops, analyzing graph structures, and validating data integrity.

How it works
- • Uses DFS with recursion stack
- • White nodes: unvisited
- • Gray nodes: in recursion stack
- • Black nodes: completed
- • Cycle found when back edge detected
