WebIn the above code, each array is initialized separately, and subsets are printed in separate code blocks. The my_array, my_2d_array, and my_3d_array are the 1D, 2D, and 3D arrays, respectively, and subsets are printed using the indexing notation. In the first example, we use slicing to select the items at index 0 and 1 of my_array. cory wiese yeti
