Exercise 2: Consider the following class: public class Sequence { private ArrayList values; public Sequence() { values = new ArrayList(); } public void add(int n) { values.add(n); } public String toString() { return values.toString(); } } Add a method public Sequence merge(Sequence other) that merges two sequences, alternating ele- ments from both sequences. If one sequence is shorter than the other, then alternate as long as you can and then append the remaining elements from the longer sequence. For example, if a is 1 4 9 16 and b is 9 7 4 9 11 then a.merge(b) returns the sequence 1 9 4 7 9 4 16 9 11 without modifying a or b.
