Given the following method within the IntList class:

public IntList f() { if(head == null)

return null;

IntNode t = new IntNode(head.getNum(), null); for(IntNode pl = head, p2 = t; pl != null; pl = pl.getNext())

if(pl.getNum()> p2.getNum()) { p2.setNext(new IntNode(pl.getNum(), null));

p2p2.getNext();

}

IntList res = new IntList(); res.head = t;

return res;

A. (7 points) What will the method f return for the list -
