(Add synchronization to your solutions to HW 3 to eliminate all of the race conditions. You should not remove any of the sleep() commands that you used to produce the race conditions, but simply add the necessary mutex synchronization calls. Your writeup should include high level pseudocode explaining the logic of your synchronization strategy using ordinary semaphores (init, p(), v()); your implementation should use the synchronization primitives of the programming API you are using (Posix & Win32). Submit design documentation, wellXcommented source code & annotated output for this part of the assignment.
