At an instant, the resource allocation state in a system is as follows:
4 processes P1–P4
4 resource types: R1–R4
R1 (5 instances), R2 (3 instances), R3 (3 instances), R4 (3 instance)
Snapshot at time T₀:

Run the deadlock detection algorithm and test whether the system is deadlocked or not. If it is, identify the processes that are deadlocked.
