Given two arrays, A and B 1 2 3 4 1 5 9 13] 5 6 7 8 2 6 10 14 A = B = 9 10 11 12 3 7 11 15 [13 14 15 16] 4 8 12 16] Python Practicing with library functions: Write code to compute the sum of all elements on the 2D A-array. Use loops Use the numpy.sum function Transfer the diagonal elements of A to the diagonal elements of B. Multiply element-by-element the 3rd column of A times the 3rd row of B. As (3)(3), (7)(7), etc. Store the result in the column vector C (for python this is a 2D array). Use loops, can't use slicing Slicing is allowed Write code to delete the first and third column of the "A" 2D array.
