Drawbacks of Sets and Linked Lists
(continued)
Now you can use your node to store data
and link with other nodes.
If you mess up on any one of those steps, your
linked list won’t work, and because linked lists
use pointers, your pointers could point anywhere
in memory, causing all sorts of random
problems. The moral is that linked lists are a
powerful and flexible data structure, but they
come at a price of added complexity for the
programmer. Accidentally create one dangling
pointer, and you can bring your entire program
crashing to a halt.
