Let n be the actual number of data values in each list. Store the product of corresponding elements of x and y in a third array, z, also of size 20 . Display the arrays x,y, and z in a three-column table. Then compute and display the square root of the sum of the items in z. Note: Sqrt should be rounded to 2 digits.
