Question:
Find the number of vertices that must pass through from one edge to another in the graph.
Ideas:
The first step must be through the cut point. Therefore, we can first connect the nodes and then contract the point to form a tree. The path on the tree is "non-cut point-not cut ". point-cut point -..." In this mode, the path U-> V only needs to find their LCA, and the answer can be calculated through (DIS [u] + dis [v]-Dis [LCA] * 2)/2.
Note:
This point is reduced by the edge, because it
1. If power and flow are not taken into account, simply inherit the runnable in the corresponding activity, write a while loop inside the Run method, call the interface to return the data, and update the UI immediately if the data has changed2. Need to consider the power, is the remote server to send messages to the client, the client receives information, to send a broadcast, the corresponding activity received the broadcast to update the UI, the broadcast sender is a background service compone

How can you actually get faster access to your reports without increasing the burden on your servers?If you repeatedly access the same report repeatedly, the server's operation consumption will increase, and the time required for the presentation of the report will grow. If you can cache the first calculated report and read it directly from the cache when it is accessed again, this can reduce the burden on the server, thus reducing the user's waiting
Note: micro-credit real-time dialogue is required for traffic costs, so you try to use the WiFi network, because the small series test this call by flow is more expensive than the phone.

I've tried both ways, but Walk-forward is better for this task because it's directly related to the goal of the competition: using historical values to predict future values. But the segmentation destroys the data points at the end of the time series, making it difficult to train accurate predictions of future models.S
, this allows real-time tasks to run in a different way than time-based tasks.
