Solution: Linked List Cycle
Explore how to determine if a linked list contains a cycle by implementing the fast and slow pointer technique. Understand how the pointers move at different speeds to detect cycles in one pass without extra memory, helping you optimize linked list traversal problems.
Statement
Given the head of a linked list, determine whether the list contains a cycle. A cycle exists if a node in the list can be revisited by continuously following the next pointers. Return TRUE if a cycle is present; otherwise, return FALSE.
Constraints:
Let n be the number of nodes in a linked list.
