PART B: Spiral Path Build a python function called spiral path that takes a two-dimensional list as an argument and returns a one-dimensional list with the values of the original 2d list that are arranged by spiralling through it (starting from the top-left). Examples: spiral_path([ [1, 2], [5, 0] ]) [1, 2, 0, 5] spiral_path([ [1, 2, 3], [8, 9, 4], [7, 6, 5] ]) [1, 2, 3, 4, 5, 6, 7, 8, 9] spiral_path([ [1, 1, 1], [4, 5, 2], [3, 3, 2] ]) [1, 1, 1, 2, 2, 3, 3, 4, 5] Write a python script called spiral.py that will test all cases described above
