Assume that you have implemented a sequence class. Describe the mySequence object (i. e., items with the correct order and the position of the current index) after each line of the following code sequence mySequence;
mySequence. insert(3)
mySequence. insert(2);
mySequence. attach(10);
mySequece. advance();
mySequence. attach(11);
mySequence. insert(4);
mySequence. insert(6);
mySequece. advance();
mySequence. remove_current();
mySequence. insert(9);

The final sequence is:  2 10 3 6 9(c) 11

Explanation:

The first line of code creates the sequence object "mySequence". Every insert() method inserts the item before the current item to make a new current item. The attach() method adds a new current item after the previous current item. The advance() method makes the next item to the current item the new current item.

The remove_current method of the sequence object removes the current item of the sequence.
