Processes p1, p2, and p3 are executing concurrently. The variables x, y, and z are binary semaphores, all initialized to 1. The left arrow points to the currently executing instruction. pl: P(x) ... P(z) <-- p2: P (Y) ... p3: ... P(Z) ... P(x) <-- P(x) <-- a) To determine if the state is a deadlock state, draw a resource allocation graph by interpreting each semaphore as a resource containing 1 unit and each P operations as request for the resource. b) Reduce the graph to determine if the state contains a deadlock. c) Would initializing any of the semaphores to a value greater than 1 avoid the deadlock?
