Suppose two processes are using shared memory as shown below: give the possible values than can be printed for b and c by EACH process. Assume all C language assignment statements are atomic: P0 executes shared int a: int b, c b = 1: a = b: c = a: Print (b, c): P1 executes: shared int a: int b, c a = 100: b = a: c = b + a: Print (b, c) You are asked to design concurrency control mechanisms for a two different hardware architectures: the first supports a Test-and-Set and a the other supports a swap instruction: as follows: int Test-and-Set(int target) { int temp = target: target = true: return (temp): } void Swap (int *a, *b) { int temp: temp = *a: *a = *b: *b = temp: } Does the swap works similarly as Test-and-set
