Say I have a Binary Semaphore S initialized to 1.

Consider V() as Signal and P() as Wait. If I now invoke V(S), will it wait for S to become 0? Or will it go on with further execution without making any changes to S?

When we perform any operation on a binary semaphore untill that operation is performed completely the process will wait untill a value is encountered on which the given semaphore operation can be performed . In the given question in the binary semaphore S untill it becomes 0 the signal operation can't be done and unless that statement is executed the control will not move on to the following statement.
