Suppose a program P has the following three threads Thread1, Thread2, and Thread3, and a shared counter, count, as shown below: int count = 10; Semaphore Lock = 1; // initial value is 1 Thread1(...) ( 1 Thread2(...) { } // do something Lock. Wait(); count++; Lock.Signal(); { // do something Lock. Wait(); count- Lock.Signal(); Thread3(...) // do something Lock. Wait(); printf("%d", count); Lock Signal(); Upon the execution of the program P, the number of possible orders of execution of threads where the output will be 10 is Note: The above three threads are non-preemptive threads.
