Consider the following scenario. A system has three resourcetypes; R1 has 3 instances, R2 has 4 instances, R3 has 5. There arethree processes, A-C, whose code is given below.

ProcessA {

Acquire(R3, 2);

Acquire(R2, 1);

Acquire(R2, 1);

if (condition1) Acquire(R3, 1);

else Acquire(R1, 1);

ReleaseAllResources();

}

ProcessB {

Acquire(R2, 1);

Acquire(R3, 1);

Acquire(R1, 1);

if (condition2) Acquire(R2, 2);

else Acquire(R2, 1);

ReleaseAllResources();

}

ProcessC {

Acquire(R1, 2);

Acquire(R3, 2);

Acquire(R2, 1);

if (condition3) Acquire(R3, 1);
