b) Consider the following three-process concurrent program which uses semaphores S1, S2, and S3: Process P1 Process P2 Process P3 L1: L2: L3: P(S1); print(“U"); V(53); P(S3); P(S2); print("E");...

URGENT!!!!

Extracted text: b) Consider the following three-process concurrent program which uses semaphores S1, S2, and S3: Process P1 Process P2 Process P3 L1: L2: L3: P(S1); print(“U"); V(53); P(S3); P(S2); print("E"); print("W"); V(S2); V(S1); goto L1; goto L2; goto L3; Evaluate if there are initial values that can be given to the semaphores so that the processes cooperate to print the string UWEUWEUWEUW. If so, give the initial values (identify which value is to be used for which semaphore) and explain how the string is printed. Assume that the statement "print" will print the corresponding letter and the statement "goto" will take the control back to the corresponding level.
