Your program should:

1. Open the text file “ass3.txt”. (Note: “ass3.txt” should be a hardcoded as a constant.)

2. Read a graph from the file.

The data files are constructed as follows:

• Two integers: nVertices and nEdges, the number of vertices and edges in the graph.

• nVertices triples consisting of the label and the x- and y-coordinates of each vertex.

• nEdges triples consisting of the labels of the start and end vertices of each edge, along with its weight. Note: the weight associated with an edge will be greater than or equal to the Euclidean distance between its start and end vertices as determined by their coordinates.

• Two labels, the indicating the start and goal vertices for which the paths are required.

Read the data file into adjacency lists, or an adjacency matrix, and print on the screen the first 5 vertices and the vertices they are connected to together with their weights. e.g.:

a:  c(35)  d(27)  e(48)

b:  d(35)  g(27)

c:  b(125) e(20)  f(56)  h(31)

. . .
