3

» A data structure consisting of a group of nodes which together represent a sequence. » Example: » Linked List with Header: 4 © Sekolah Tinggi Teknik Surabaya Next Property Node Class Element Value Property

» Store its element in Node Class » Each Node have next reference to hold next element » Linked List Class have header » Last element is Nothing/Null » If header is null then the linked list is empty 5 © Sekolah Tinggi Teknik Surabaya

6

» Start with header, trace its next » Example: Finding Bacon 7 © Sekolah Tinggi Teknik Surabaya It is Bacon ?

» Example: Inserting Cookies After Eggs » Create Node Cookies » Find Node Eggs, get its Next (Bacon) » Set Cookies’s Next to Bacon » Set Eggs’s Next to Cookies 8 © Sekolah Tinggi Teknik Surabaya

» Example: Removing Bacon » Find Bacon » Get Bacon’s Previous Node (Cookies) » Get Bacon’s Next Node (Nothing) » Set Cookies’s Next to Nothing 9 © Sekolah Tinggi Teknik Surabaya
