Computer Science / Unit 3 CS 0104 short lesson, about 20 seconds
The Linked List
Captions available
The idea
A linked list is a list data structure where each element holds a link to the next — access is sequential; insertion and deletion run fast.
In practice
Train cars couple and uncouple anywhere in minutes, but reaching car forty means walking through thirty-nine.
Where people slip
Fast entry, slow arrival — the mirror of the array list.
