Devise an algorithm for constructing the spanning forest of a graph based on depth-first searching.
What is wrong with the following โproofโ using mathematical induction of the statement that every tree with \({\bf{n}}\) vertices has a path of length \({\bf{n - 1}}\). Basis step: Every tree with one vertex clearly has a path of length \(0\). Inductive step: Assume that a tree with \({\bf{n}}\) vertices has a path of length \({\bf{n - 1}}\), which has \({\bf{u}}\) as its terminal vertex. Add a vertex \({\bf{v}}\) and the edge from \({\bf{u}}\)to \({\bf{v}}\). The resulting tree has \({\bf{n + 1}}\) vertices and has a path of length \({\bf{n}}\). This completes the inductive step.
