You are given a directed graph G(V,E) with n vertices and m edges. Let S be the subset of vertices in G that are able to reach some cycle in G. Design an O(n + m) time algorithm to compute the set S. You can assume that G is given to you in the adjacency-list representation.

Consider an undirected graph G that has n distinct vertices. Assume n≥3. How many distinct edges will there be in any circuit for G that contains all the vertices in G? What is the maximum degree that any vertex in G can have? What is the maximum number of distinct edges G can have? What is the maximum number of distinct edges that G can have if G is disconnected?

An m × n grid graph has m rows of n vertices with vertices closest to each other connected by an edge. Find the greatest length of any path in such a graph, and provide a brief explanation as to why it is maximum. You can assume m, n ≥ 2. Please provide an explanation without using Hamilton Graph Theory.

Consider the m by n grid graph: n vertices in each of m rows, and m vertices in each of n columns arranged as a grid, and edges between neighboring vertices on rows and columns (excluding the wrap-around edges in the toric mesh). There are m n vertices in total. a)What is the diameter of this graph? b) From the top left vertex to the bottom right vertex, how many shortest paths are there? Please explain.
