Author: Whitaker Brand (on 2016/09/08)

Write a method removeRange that accepts a starting and ending index as parameters and removes the elements at those indexes (inclusive) from the list. For example, if a variable list stores the following values:

[8, 13, 17, 4, 9, 12, 98, 41, 7, 23, 0, 92]

And the following call is made:

listRange.removeRange(3, 8);

Then the values between index 3 and index 8 (the value 4 and the value 7) are removed, leaving the following list:

[8, 13, 17, 23, 0, 92]

You should throw an IllegalArgumentException if either of the positions is negative. Otherwise you may assume that the positions represent a legal range of the list (0 ? start index ? end index < size of list).

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
    ...
}
