This problem is related Sequential Consistency. Consider the following code segments executed by 3 threads.

Thread1? Lock a=1 print(b,c) Unlock

Therad2 Lock b=2 print(a,c) Unlock

Thread3 Lock c=3 print(a,b) Unlock

a). Assume that initially all variables are set to zero. generated by the print statements.

Show at least 3 different correct outputs

b). Now consider the same code without using locks.

Thread1 a = 1 print(b,c)

Therad2 b = 2 print(a,c)

Thread3 c =3 print(a,b)

Show 3 possible correct outputs, based on sequential consistency, but different from those you have shown in part (a).
