A singly-linked list structure, implementing a list with three integer elements. The term list is also used for several concrete data structures that can be used to implement abstract lists, especially linked lists and arrays. In some contexts, such as in Lisp programming, the term list may refer specifically to a linked list rather than an array.
height ^ height ifNil: [height:= 2.0]. The 'non-lazy' alternative is to use an initialization method that is run when the object is created and then use a simpler accessor method to fetch the value. initialize height := 2.0 height ^ height
In computer programming, a variable-length array (VLA), also called variable-sized or runtime-sized, is an array data structure whose length is determined at runtime, instead of at compile time. [1] In the language C , the VLA is said to have a variably modified data type that depends on a value (see Dependent type ).
Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})
This is a list of well-known data structures. For a wider list of terms, see list of terms relating to algorithms and data structures. For a comparison of running times for a subset of this list see comparison of data structures.
College football has never been safe for the sane of mind, but the 12-team playoff seems to have sent it over the cliff.
A stack is then a pointer to the "head" of the list, with perhaps a counter to keep track of the size of the list: structure frame: data : item next : frame or nil structure stack: head : frame or nil size : integer procedure initialize(stk : stack): stk.head ← nil stk.size ← 0
