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
