The only way to add people to the line is to find the right spot and decouple that connection, then insert the new person or people. Operating systems use doubly linked lists to manage the process scheduling. I noticed in one of your comments you asked about why the pointer matters. To use and manipulate linked lists of images. It might be good to add that the blind man can go through them very quickly, e.g. code. In operating systems one may use a linked list to keep track of what processes are running and what processes are sleeping a process that is running and wants to sleep gets removed from the LinkedList that keeps track of running processes and once the sleep time is over adds it back to the active process LinkedList, Maybe newer OS are using some funky data structures linked lists can be used there. This Linked list is a type of linear data structure where data elements are linked in a list using pointers. scrollbar and repaint the canvas. Prerequisites: Python GUI tkinter, Python: Pillow.
