node*

>&A

hefur er �etta "pointer" e�a reference e�a
>hva� ?

�etta er tilv�sun � bendi � node(!)

�st��an fyrir �essari ger� vi�fangs er a� vi� viljum geta breytt bendinum sem vi� sendum inn. Reyndar sendum vi�
inn t�ma benda A og B, �v� vi� lok fallsins eiga �eir a� benda � sitthvorn listann. �ess vegna eru �eir
tilv�sunarvi�f�ng.

Athuga�u a� node* er eins og hvert anna� tag. �� veist �rugglega hva� er a� gerast �:



  void fall( int &i, int &j )

� fyrra d�minu er bara node* (�.e. hn�tabendir) � sta� int. � b�kinni fela �eir �etta oftast me�
"typedef node* link;", �� geta �eir skrifa�:



void skipta(link L, int x, link &A, link &B )

�g veit ekki hvort �etta er sk�rara.
