Question

Will it causing deadlock? How do we fixed it?

P1:                                   P2:

Wait(S);                               Wait(Q);                     
Wait(Q);                               Wait(S);
........                               .............
Signal(S);                             Signal(Q);
Signal(Q);                             Signal(S);
