SLList wrong function addAfter

[changliu98]

Line 120

protected void addAfter(Node u, Node v) {
		v = u.next.next;
		u.next = v;
		if (u == tail) 
			tail = v;
}

the v=u.next.next; seems wrong, this function will only delete the node after u

The solution is to make v = u.next.next; --> v.next = u.next;
