five vehicles were to come, the janitor would allow three of them to enter the barrier, then put down the car, the rest of the car must wait at the entrance, and then the car will have to wait at the entrance. At this time, there is a car left the parking lot, the janitor learned, open the car block, put in a car, if you leave two again, then can put two, so reciprocating. in this parking system, parking spaces are public resources, and each car is like a thread, and the

Brief introductionThe semaphore (Semaphore), sometimes called a semaphore, is a facility used in a multithreaded environment that coordinates individual threads to ensure that they are able to use public resources correctly and rationally.ConceptThe semaphore is divided into single-valued and multi-valued two, which can only be obtained by one thread, the latter of which may be obtained by several threads.Take a car park operation as an example. For the sake of simplicity, suppose the parking lo
