Write a method split that rearranges the elements of a list so that all of the negative values appear before all of the non-negatives.

For example, suppose a variable list stores the following sequence of values: [8, 7, -4, 19, 0, 43, -8, -7, 2] The call of list.split(); should rearrange the list to put the negatives first.

One possible arrangement would be the following: [-4, -8, -7, 8, 7, 19, 0, 43, 2] But it matters only that the negatives appear before the non-negatives. So this is only one possible solution. Another legal solution would be to rearrange the values this way: [-7, -8, -4, 2, 43, 0, 19, 7, 8]

You are not allowed to swap data fields or to create any new nodes to solve this problem; you must rearrange the list by rearranging the links of the list. You also may not use auxiliary structures like arrays, ArrayLists, stacks, queues, etc, to solve this problem.

Assume that you are adding this method to the LinkedIntList class as defined below: public class LinkedIntList { private ListNode front;//null for an empty list ellipsis }
