Detect a cycle in a linked list.
AI-Expanded — inferred from the question title, not from the original candidate report
Given the head of a singly linked list, determine if the list contains a cycle by checking if any node can be reached again by continuously following the next pointer. If a cycle exists, return true; otherwise, return false, ensuring your solution operates with O(1) memory complexity.
Context & Summary
30-minute virtual interview covering topics like IPC mechanisms, semaphores, scheduling algorithms in multicore processors, process vs thread, storage classes in C, interrupts, and DSA questions. DSA questions included linked list operations, bit manipulation, and endianness detection.
