Consider a system consisting of two processes, P0 and P1, each accessing two semaphores, S and Q, set to the value 1: P0 P1 wait(S); wait(Q); wait(Q); wait(S); . . . . . . signal(S); signal(Q); signal(Q); signal(S); In the above situation, there is a potential deadlock scenario involving processes P0 and P1 and semaphores S and Q. Draw the resource-allocation graph that illustrates deadlock under the scenario presented in this situation.
