Write a method called reverse3 that accepts an ArrayList of integer values as a parameter and reverses each successive sequence of three values in the list. If the list has extra values that are not part of a sequence of three, those values are unchanged. For example, if a list stores values [3, 8, 19, 42, 7, 26, 19, -8 ], after the call the list should store the values [19, 8, 3, 26, 7, 42, 19, -8]. The first sequence of three (3, 8, 19) has been reversed to be (19, 8, 3). The second sequence ( 42, 7, 26 ) has been reversed to be (26, 7, 42 ), and so on. Notice that 19 and —8 are unchanged because they were not part of a sequence of three values.
