How do I create comparison function to be passed to a flexible selection sort function. The comparison function should enable the sort function to arrange the elements of a list in the following order: for example a list containing 2, 1, 10, 4, 3, 6, 7, 9, 8, 5 would be transformed into 2, 4, 6, 8, 10, 1, 3, 5, 7, 9. The function must physically rearrange the elements within the list not just the elements in the desired order.
