Design a queue and analyze tradeoffs
OptiverSoftware Engineer · Technical ScreenLast updated
This question evaluates understanding of FIFO data structures, algorithmic complexity analysis, memory and cache behavior, and concurrent access concerns.
Design a FIFO queue data structure that supports enqueue, dequeue, peek, and isEmpty. Compare implementations using a singly linked list, a dynamic array, and a circular buffer. Analyze time and space complexity, amortized costs of resizing, memory overhead, and cache locality. Discuss edge cases such as underflow and overflow, potential blocking vs. non-blocking behavior for concurrent access, and when each implementation is preferable.
