Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a system with available resources of [3, 2, 2] and processes with maximum needs of P1 [7, 5, 3], P2 [3, 2, 2], and P3 [9, 0, 2], and current allocations of P1 [0, 1, 0], P2 [2, 0, 0], P3 [3, 0, 2], determine if a request of [2, 1, 1] from P1 leaves the system in a safe state.

💡 Hint: Check if you can finish all processes with the hypothetical allocation.

Challenge 2 Hard

Describe a scenario where a process requests resources leading to an unsafe state. Detail how this can be identified and managed.

💡 Hint: Use a diagram of resource allocation for clarity.
