a. Write a function called rotateForward that accepts a list as a parameter and uses a list comprehension to move the last element of the list into the first position. i. rotateForward([1,2,3,4]) will return [4,1,2,3] ii. rotateForward([17, 'ok',0.0,'x']) will return [['x',17,'ok',0.0]] b. Write a function called rotateBackward that accepts a list as a parameter and uses a list comprehension to move the first element of the list into the last position. i. rotate Backward([1,2,3,4]) will return [2,3,4,1] ii. rotate Backward([17,'ok',0.0,'x']) will return [['ok',0.0,'x',17]]
