Linked Lists:(important) example code would help a lot.
Insertion, Deletion of a node, deletion of the list, finding a data value within the list
Can be made to follow rules like being sorted
Insertion or deletion requires altering the pointers in the list so that the rest of the list is intact around the changed area
