The following program consists of 3 concurrent processes and 3 binary semaphores.The semaphores are initialized as S0 = 1, S1 = 0, S2 = 0.
|
Process P0
|
Process P1
|
Process P2
|
|
While (true)
{
wait (S0);
print '0';
release S1;
release S2;
}
|
Wait (S1);
release (S0);
|
Wait (S2);
release (S0);
|
How many time process P0 print '0'?
a. Exactly 2 time
b. Exactly 3 time
c. Atleast 2 time
