Assume you have three processes, P1 P2 and P3 share a semaphore for process synchronization and the initial value of semaphore is 1. Let the negative value of semaphore imply the number of processes in the waiting queue. Processes access the semaphore in the following orders: P3 needs to access P2 needs to access P1 needs to access P3 leaves the critical section P3 needs to access P2 leaves the critical section P2 needs to access P1 leaves the critical section P1 needs to access P3 leaves the critical section The final value of this semaphore will be: 01 0 2 -1
