Each question below lists two or more sequences of lock acquisition and releases. Given each group of sequences, state whether deadlock can occur and if so give one possible sequence that results in deadlock. 1. a1. LOCK(A); a2. LOCK(B); a3. LOCK(C); a4. UNLOCK(A); a5. UNLOCK(B); a6. UNLOCK(C); b1. LOCK(B); b2. LOCK(C); b3. UNLOCK(B); b4. UNLOCK(C); 2. a1. LOCK(A); a2. LOCK(B); a3. LOCK(C); a4. UNLOCK(A); a5. UNLOCK(B); a6. UNLOCK(C); b1. LOCK(C); b2. LOCK(B); b3. UNLOCK(B); b4. UNLOCK(C); 3. a1. LOCK(A); a2. UNLOCK(A); a3. LOCK(B); a4. UNLOCK(B); a5. LOCK(C); a6. UNLOCK(C); b1. LOCK(C); b2. LOCK(B); b3. UNLOCK(B); b4. UNLOCK(C);

Deadlock is when one process is wait for another proce

Each inquiry beneath lists span or further continuitys of lock wages and discharges. Impartn each class of continuitys, declare whether deadlock can arise and if so impart single practicable continuity that results in deadlock.
