a)
1 is false and 2 is true
b)
Both 1 and 2 are false
c)
1 is true and 2 is false
d)
Both 1 and 2 are true

If after checking the condition (critical - flag == FALSE) P₁ preempts without making critical flag TRUE and in turn gives option for P₂ to check the condition and since critical - flag is FALSE till this point. P₂ will also enter the if block and make the critical - flag as TRUE and start assessing critical -region ().
If P₁ again comes back, it will start from time 2 directly and rewrite critical - flag as TRUE again and will start assessing critical - region (). So, it is possible for P₁ and P₂ to access critical - region concurrently.
Since, mutual exclusion is mandatory condition for deadlock, deadlock will never occur in this case. However, consistency can’t be ensured in such cases.

View answer

Consider three concurrent processes P1, P2 and P3 as shown below, which access a shared variable D that has been initialized to 100.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 __________. Correct answer is '80'.
