F. I need help with this discrete math problem!

Let's consider an undirected graph G = (V, E). An independent subset is a subset I C V such
that for any vertices, i, j E I and there is no edge between i and j in E. A set i is a maximal
independent set if no additional vertices of V can be added to I without violating its
independence. Note, however, that a maximal independent set is not necessarily the largest
independent set in G. Let a(G) denote the size of the largest maximal independent set in G.
1. What is a(G) if G is a complete graph on n vertices? What if G is a cycle on n vertices?
