Adjacency Matrix Graph
Objective:
Create a class which constructs an adjacency matrix
representation of a graph and performs a few graph operations.
Write an Adjacency Matrix Graph class which has the
following:
Two constructors:
Default which makes the matrix of a pre-defined size
Parameterized which takes in a non-negative or 0 size and
creates an empty matrix
addEdge: this method returns nothing and takes in two string
parameters and a weight. The two integer parameters correspond to
the...

Given a plane graph represented as an ordered (clockwise) adjacency lists, as presented in class, give a detailed efficient algorithm that lists all regions of the plane embedding. Here each region is a sequence of vertices, ordered as one traverses the edges of its boundary. See the following example. Do analysis on the running-time of your algorithm. Note that all planar graphs have O(n) edges.
Execute DFS on the graph below, starting in node a. Whenever you have a choice which...
Execute DFS on the graph below, starting in node a. Whenever you have a choice which vertex to visit next, choose the next vertex in the adjacency list of the vertex (e.g., when you have reached node e, you must first try to visit node f, then g, and then . Indicate the outcome of the algorithm by labeling the edges of the graph either as T (tree edge) F (forward edge), B (back edge), or C (cross edge). Label...

Q2. Show the execution trace of DFS on the following directed graph. You must show discovery time v.d, finish time v.f, and the v.color for each node as the algorithm progresses. Indicate all tree edges, back edges, forward edges, and cross edges when the final DFS forest is constructed. Assume that the edges going out from a vertex are processed in alphabetical order and that each adjacency list is ordered alphabetically.
