Question 1: The following program consists of 3 concurrent processes and 3 binary semaphores. The semaphores are initialized as S0 = 1, S1 = 0, S2 = 0. Process PO Process P1 Process P2 while(true) { wait (S0); print '0'; signal(S1); signal(S2); wait(S1); signal(SO); wait(S2); signal(S0); What is the maximum number of times that PO can print "0"?
