Messaging sends a message to an instance, and the runtime uses the Objc_msgsend function to send it. Each class has a pointer to his super class, with a dispatch table that points to the address of each method.  Each instance (from NSObject or

Because all integers can be uniquely decomposed, P1^a1*p2^a2*...*pi^ai, and the number of queries can be decomposed into P1^a1k*p2^a2k*...*pi^aik, this inquiry will all a1>=a1k && A2 >= A2K &&The number of A3 >= a3k is separated from the original
