Consider three concurrent processes P1, P2 and P3 as shown below, which access a shared variable D that has been initialized to 100. Refer to the table below. The processes are executed on a uniprocessor system running a time-shared operating system. If the minimum and maximum possible values of D after the three processes have completed execution are X and Y respectively, then the value of Y − X is _______.
