Practice Confluent Coding Question | Real Coding Interviews

Quick Summary

Implement a dynamically expanding integer queue supporting insertion, removal, and random access.
All core operations must guarantee O(1) time complexity regardless of queue size.
Gracefully handle edge cases such as polling or getting random values from an empty structure.

What This Tests

Combining multiple data structures to satisfy conflicting performance requirements.
Achieving O(1) arbitrary deletion from an indexed collection.
Maintaining synchronization between ordered traversal structures and random-access collections.
Understanding space-time tradeoffs in concurrent data structure updates.
