Cse 120

Suppose you were implementing a counting semaphore in a new operating system for a mobile phone. Even though in CSE 120 you were told that counting semaphores were unbounded, you know that in practice there is a maximum value which will be imposed by the exact representation you use. In your case, the maximum value is 2^32.
