Noun
linked list (plural linked lists)
(computer science) A simple linear data structure, each of whose nodes includes a pointer to the next (and sometimes previous) node in the list, enabling traversal of the structure in at least one direction from any starting point.
However, in this case, the handle should be a single pointer to the dummy node itself. citation Linked list operations When manipulating linked lists in-place, care must be taken to not use values that you have invalidated in previous assignments. Source: Internet
