I need to connect P1 to P6 and also P3 to P7 (there is P1 to P7 and P1 needs to be connected to P6 while P3 to P7 do i make a separate line for P1 to P6, how do i answer the question?) and write a pseudo code using semaphore to control the execution process how to do it(the pseudo code is like describing the whole thing happening while adding semaphore to better control it)?
