HTML offers three ways for specifying lists: ordered lists, unordered lists, and description lists. Ordered lists use ordinal sequences to indicate the order of list elements, unordered lists use a defined symbol such as a bullet to list elements in no designated order, and description lists use ind...

The C language does not define a linked list data structure. If you are using C and need a linked list, you either need to use a linked list from an existing library (such as GLib) or write your own linked list interface. This topic shows examples for linked lists and double linked lists that ca...

[] // an empty list. head::tail // a construction cell holding an element, head, and a list, tail. :: is called the Cons operator. let list1 = [ 1; 2; 3 ] // Note the usage of a semicolon. let list2 = 0 :: list1 // result is [ 0; 1; 2; 3 ] let list3 = list1 @ list2 // result is [ 1; 2; 3; 0...

The List (linked list) shines in sequential access: accessing the first element prepending to the front of the list deleting from the front of the list On the other hand, it's not ideal for random access (ie. getting nth element) and traversation in reverse order, and you might have better...

empty list constructor [] :: [a] non-empty list constructor (:) :: a -> [a] -> [a] head - returns the first value of a list head :: [a] -> a last - returns the last value of a list last :: [a] -> a tail - returns a list without the first item tail :: [a] -&gt...

map = %{} // creates an empty map map = %{:a => 1, :b => 2} // creates a non-empty map list = [] // creates an empty list list = [{:a, 1}, {:b, 2}] // creates a non-empty keyword list Elixir provides two associative data structures: maps and keyword lists. Maps are the Elixir key-...

A list is an ordered collection of values. In Java, lists are part of the Java Collections Framework. Lists implement the java.util.List interface, which extends java.util.Collection. ls.add(E element); //Adds an element ls.remove(E element); //Removes an element for(E element : ls){} //Iter...

While an Erlang string is a list of integers, an "iolist" is a list whose elements are either integers, binaries or other iolists, e.g. ["foo", $b, $a, $r, <<"baz">>]. That iolist represents the string "foobarbaz". While you can convert an iolist ...
