, so think of the base ring tree, but the problem is not said to be connected, so is a base ring tree forest.Then each time you find the connecting block, then the DP can be.The DP should break off a chain on the ring, and then compute the root of the disconnected two endpoint root and _root respectively.Root is rooted, the root must not take, _root may not take. _root is the same as root.DP equation: f[i][1] Table I take the time with I as the root o

Title Link: BZOJ-1040Problem analysisThe model of this problem is a graph, not necessarily connected, each connecting block points equal to the number of sides.Each connected block is a base ring + outward tree. An edge is added to the tree.If it is a tree, it can be directly tree-shaped DP. However, this is the base ring + outward tree, you need to find an edge on the ring, record the edge of the two endpo
