5. A user defined semaphore programmed was written for SemTake and SemGive with one global variable, which was updated on semtake/give.
Question was to point out if that program will work as per semTake/semGive requirement or not? What may be the problem with that?

So, the second process may even take the sem.Which lead to problem ) . What could be a solution to it?
