Chapter 12.1, Problem 26E
A forest is a graph every component of which is a tree or equivalently, a graph without cycles.
[BB] explains why a forest is the disjoint union of trees.
Show that a forest with c components, each containing at least two vertices, has at least 2c vertices of degree 1.
Is the result (b) true without the stipulation that each component contain at least two vertices? Explain.
Find a formula for the number of edges in a forest with n vertices and c components and prove your answer
