In computer science, a dynamic array, growable array, resizable array, dynamic table, mutable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern mainstream programming languages.
Lists are typically implemented either as linked lists (either singly or doubly linked) or as arrays, usually variable length or dynamic arrays.. The standard way of implementing lists, originating with the programming language Lisp, is to have each element of the list contain both its value and a pointer indicating the location of the next element in the list.
List of applications and frameworks that use skip lists: Apache Portable Runtime implements skip lists. [9] MemSQL uses lock-free skip lists as its prime indexing structure for its database technology. MuQSS, for the Linux kernel, is a CPU scheduler built on skip lists. [10] [11] Cyrus IMAP server offers a "skiplist" backend DB implementation [12]
A dynamic array is a data structure that allocates all elements contiguously in memory, and keeps a count of the current number of elements. If the space reserved for the dynamic array is exceeded, it is reallocated and (possibly) copied, which is an expensive operation. Linked lists have several advantages over dynamic arrays.
In computer science, a hashed array tree (HAT) is a dynamic array data-structure published by Edward Sitarski in 1996, [1] maintaining an array of separate memory fragments (or "leaves") to store the data elements, unlike simple dynamic arrays which maintain their data in one contiguous memory area. Its primary objective is to reduce the amount ...
A drop-down list or drop-down menu or drop menu, with generic entries. A drop-down list (DDL), drop-down menu or just drop-down [1] – also known as a drop menu, pull-down list, picklist – is a graphical control element, similar to a list box, that allows the user to choose one value from a list either by clicking or hovering over the menu.
Most standard objects contain an array of drop-down lists, properties windows, and triggers that allow the user to customize the logic required for an accurate model of the system. FlexSim also includes a flowcharting tool to create the logic for a model using pre-built activity blocks.
If you are using more than one drop down list on the same page this parameter is very important. The Id parameter for each list should be different and unique (if using more than one on the same page). Hence the for example {{Drop down list|Name=text1|id=IdName1|Value1=a|Value2=b|Value3=c}}
