WebYou are given a forest — an undirected graph with nn vertices such that each its connected component is a tree. The diameter (aka "longest shortest path") of a connected undirected graph is the maximum number of edges in the shortest path between any pair of its vertices. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
Web【Problem Description】 First define the diameter of a tree that is the longest of the shortest distances of any two points on the tree. Intention: Give you a forest, merge all the trees in the forest into one tree, and make the final diameter of the tree the shortest.
