Draw figures representing our abstract view of the structures created by each of the following code sequences.

a.

LLStringNode node 1 = new LLStringNode ( " alpha " ) ;

LLSt ringNode node 2 = new LLSt ringNode ( " beta " ) ;

LLStringNode node 3 = new LLStringNode ( " gamma " ) ;

node 1. set Link( node 3) ;

node 2. set Link( node 3) ;

b.

LLStringNode node 1 = new LLStringNode ( " alpha " ) ;

LLStringNode node 2 = new LLStringNode ( " beta " ) ;

LLStringNode node 3 = new LLStringNode ( " gamma " ) ;

node 1. set Link( node 2) ;

node 2. set Link( node 3) ;

node 3. set Link( node 1) ;

c.

LLStringNode node 1 = new LLStringNode ( " alpha " ) ;

node 1. set Link( node 3) ;

node 2. set Link( node 1. getLink( ) ) ;

d.
