Reported QRT coding questions
Disk Head Scheduling: Shortest Seek Time First
3/5A QRT coding question on operating-system disk scheduling: service a set of track requests under a greedy closest-first policy and account for the total distance the head travels, then compare sweep-based and arrival-order policies. It tests simulation, deterministic tie-breaking, and reasoning about starvation and complexity. The full statement and reference implementation are available to subscribers.
asked July 2026Qube RTFill Values in Graph with Conditions
3/5Investigate a graph propagation puzzle featured in QRT interviews that requires updating adjacency matrices based on specific numerical criteria. This task evaluates your capability to utilize priority queues or specialized traversal queues to propagate values across interconnected nodes until equilibrium or condition satisfaction is reached.
