Consider the following code segment: ArrayList scales = new ArrayList ();
scales. add("DO");
scales. add("RE");
scales. add("MI");
scales. add("FA");
scales. add("SO");
String swap = scales. get(2);
scales. remove(2);
String set = scales. remove(scales. size()-1);
scales. add(scales. get(0));
scales. set(0,set);
scales. add(scales. size()/2, swap);

Which of the following represents the value of scales after the code has been executed?

[SO, RE, FA, DO]

[SO, RE, MI, FA, DO]

[SO, RE, MI, DO]

[FA, RE, MI, DO]

[FA, SO, RE, MI, DO]
