In a weighted graph, edges have an associated number called weight, which might represent distances, costs times, or other quantities. The minimum spanning tree in a weighted graph minimizes the total weights of the edges necessary to connect all the vertices. Graphs can represent many real-world entities, including airline routes, electrical circuits, and job scheduling. The adjacency matrix can be used to represent a graph's edges in a computer program. Topological sorting is useful for scheduling projects which contain many tasks contingent on other tasks. There may be many correct topological sorts for a given graph. You can create a topological sort of a graph that contains cycles.

There is a matrix Q of dimension NxN, which describes the characteristies of a certain area: in each location (x,y) of the matrix Q stores the proportion of square surface in the coordinate (x,y) of the area. The mouse starts from an initial position (x0,y0), and the program should print out the coordinates of all the squares the mouse will pass throuch when it moves following the rules as follows: The mouse moves to one of the 8 surrounding squares at each step • The mouse chooses the square with the largest proportion of square surface among the 8 ones to move to • The mouse stops if all the 8 surrounding squares have lower or equal proportion of square surface with respect to the square it is currently on Example: Assuming we have the following Q matrix of size 10*10, and the mouse starts at the location (3,7). Then the mouse will move following: (3,7) (4,8) (5,8) (6,8) (7,9). And it will stop at location (7,9). 2 0.1 3 4 0.1 0.1 6. 7 0.1 10 0.1 0.2 1 0.1 0.1 0.1 0.1 0.1 0.1 0.2 0.2…
