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.
A dictionary coder, also sometimes known as a substitution coder, is a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure (called the 'dictionary') maintained by the encoder. When the encoder finds such a match, it substitutes ...
var x1 = 0; // A global variable, because it is not in any function let x2 = 0; // Also global, this time because it is not in any block function f {var z = 'foxes', r = 'birds'; // 2 local variables m = 'fish'; // global, because it wasn't declared anywhere before function child {var r = 'monkeys'; // This variable is local and does not affect the "birds" r of the parent function. z ...
[3] [4] [5] [11] In separate chaining, the array does not store the value itself but stores a pointer to another container, usually an association list, that stores all the values matching the hash. By contrast, in open addressing, if a hash collision is found, the table seeks an empty spot in an array to store the value in a deterministic ...
Using value types can result in significant performance improvements in user applications as well. [85] Array, Dictionary, and Set all utilize copy on write so that their data are copied only if and when the program attempts to change a value in them. This means that the various accessors have what is in effect a pointer to the same data storage.

Mutable (non-const) operations can then be implemented in such a way that they create new objects instead of modifying the existing ones. This approach is characteristic of functional programming and is also used by the string implementations in Java, C#, and Python. (See Immutable object.)
In the CSS stylesheet language, the tilde finds the element selected by the right-hand side that shares the parent with an element selected by the left-hand side. [ 74 ] In the D programming language , the tilde is used as bitwise not operator, concatenation operator such as those of arrays , [ 75 ] and to indicate an object destructor.
