Q7.3 Semaphores 8 Points Consider two processes P1 and P2 written in the table below and we want the following output when two processes run: GOOD BAD UGLY Time P1 P2 Ti T2 printf ("GOOD "); T3 T4 printf ("BAD "); T5 T6 printf ("UGLY ") T7 Can you put necessary synchronization tools (e.g., semaphores) around the printf calls so that the desired output is generated?
