Question: Reading is disgusting ···. That is to say, there are now n Different jacks, m different appliances, and K adapters. (The adapter is equivalent to an intermediate socket, for example, an adapter is (x, y ). There is an electrical appliance that must be inserted with an X Jack, but now there is only one y Jack, then it can be connected through an adapter ). In addition, you must note that the number of adapters is provided, and the number of e
