Linked-List: Mirror

Consider the following private class for a node of a singly-linked list of integers:

private class Node{
public int value;
public Node next;
}

A wrapper-class, called, ListImpl, contains a pointer, called start to the first node of a linked list of Node.

Write an instance-method for ListImpl with the signature:

public void mirror();

That makes a reversed copy of the linked-list pointed to by start and appends that copy to the end of the list. So, for example the list:

start 1 2 3

after a call to mirror, becomes:

start 1 2 3 3 2 1

Note: in your answer you do not need to dene the rest of the class for ListImpl just the mirror method.
