Task $1$ Write a function, nearest$\_$edge$\_$square$($x$,$ y$,$ length$),$ which returns a tuple containing an integer $(0,1,2$ or $3)$ indicating which is the nearest edge and a float for the distance to the edge. The parameters x$,$ y and length are all floats. x and y are the coordinates for the point in the square, and length is the length of square. Note: Assume the square has a lower left corner at $(0,0).$ Use integers to represent the edges of the square. The particular mapping of edges to integer values is shown in Figure $4.$ Also note that Figure $4$ contains a hint on how to compute the distance to the edges; take the perpendicular distance from the point to the edge.
