Using DASK in Python to solve this problem. Given a dask array, compute the difference along axis 0 using mean squared error This can be done without loops -- think outside of the box! This also needs to work for 1D, 2D, 3D, 4D, etc. def sequential_MSE_axis0 (anArray): # this does use the earlier MSE implementation n_elements_axis0 = anArray. shape [0] - 1 anArray.shape[0] results = da.zeros(n_elements_axis0) for i in range(n_elements_axis0): results[i] = MSE (anArray[i], anArray[i+1]) return results Complete the function below. Don't call . compute() Test Result oneDda.arange(4); print (all (isclose(a, b) for a, b in zip (MSE_axis0 (oneD), [1., 1., 1.]))) twoD = True da.arange(4).reshape((2,2)); print (all(isclose(a, b) for a, True b in zip (MSE_axis 0 (twoD), [4.]))) = threeD da.arange(8).reshape((2, 2,2)); print (all(isclose(a, b). for a, b in zip (MSE_axis0 (threeD).compute(), [16.]))) True def MSE_axis0 (anArray): ## WRITE YOUR CODE HERE

You can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e., all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array and the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed) Main method firstly constructs a 2D array of certain sizes and then construct a TwoD object and drive the task according to the above runtime interactions and displays. TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some "deep" copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e.,...

1. Write a python program that combines two arrays of the same size one-in-a-row. For instance, if a=[1,2,3,4] and b=[5,6,7,8], the combined array should be [1,5,2,6,3,7,4,8].
