Determine the minimum number of Reverse Operations that need to be
performed, in order, on the list 1, 2, 3, 4, 5, 6 so that the last number in the
list is 4 and the second last number in the list is 5 (that is, the list takes the
form (........ 5, 4).
just what is a "reverse operation"?
(a) can any two numbers be reversed, or only adjacent ones?
(b) can any sublist be reversed, or only two numbers?
