I feel that graph theory requires powerful YY capabilities... It is difficult to create a graph because this question is followed by a minimal cut process. 1: The room we want to protect in the question is the sink point T, and then we need to add an additional source point S; 2: There is an intruder room, we will connect it with the source point an arc (S, j, INF ). 3: For other rooms, if I-> J, we need to

is useful when you need to send an asynchronous live message to a user-whether the message is a notification or a page update data, while keeping the user on the same page without refreshing.

If a password parameter is input during logon, the login request will be sent to the "SDK filter plus" interface, or the interface corresponding to the "server SDK". You can develop your own server plug-in "SDK filter plus ", or call the API corresponding to the "server SDK" to process user authentication requests, mana
