Problem Statement A. (15 marks) Generate a regular lattice. Write a Python program to create a Regular Lattice graph. You are allowed to use the NetworkX package, but only the basic functions — you cannot use any graph generation routines that are built in. A regular lattice is one in which each node is connected to k nearest neighbours on either side – connecting each node to 2k other nodes effectively. Construct a regular lattice graph with 50 nodes and k=3. Plot the graph within the function, as given in the template.  B. (45 marks) Maze. Given a matrix of ‘1’s and ‘0’s that represents a maze, and the indices of the starting and finishing points, generate a NetworkX graph where each node represents a ‘1’ in the input matrix, and print: a) A list of indices in the shortest path solution to the maze (in the order of the path) b) A list of lists of indices in the isolated components of the maze (order doesn’t matter) ● ‘0’s in the input represent walls (cannot be part...
