Let there be three processes A, B and C running simultaneously on a computer system. Each of the processes continuously prints a message. Your goal is to synchronize them processes using semaphores to ensure that the message wait, wait, don't go!". Consider that the semaphores used are shared among themselves processes. Complete the processes code given in the signed points and have a green background to achieve the desired effect. Use them appropriate calls to the wait() and signal() functions to handle semaphores, as well as appropriate numerical constants where required.
