1. The following program consists of 3 concurrent processes and 3 binary semaphores. The semaphores are initialized as S0 =0, S1= 0, S2=0

Process P0	Process P1	Process P2
wait(S0); print '1'; signal(S1); signal (S2);}	wait(S1); signal (S0);	wait(S2); signal (S0);

How many times will process P0 print 1?
