In computer science, an associative array, map, symbol table, or dictionary is an abstract data type that stores a collection of (key, value) pairs, such that each possible key appears at most once in the collection. In mathematical terms, an associative array is a function with finite domain. [1] It supports 'lookup', 'remove', and 'insert ...
In Java associative arrays are implemented as "maps", which are part of the Java collections framework. Since J2SE 5.0 and the introduction of generics into Java, collections can have a type specified; for example, an associative array that maps strings to strings might be specified as follows:
Note how the use of A[i][j] with multi-step indexing as in C, as opposed to a neutral notation like A(i,j) as in Fortran, almost inevitably implies row-major order for syntactic reasons, so to speak, because it can be rewritten as (A[i])[j], and the A[i] row part can even be assigned to an intermediate variable that is then indexed in a separate expression.

BSON (/ ˈ b iː s ə n / [2]) is a computer data interchange format. The name "BSON" is based on the term JSON and stands for "Binary JSON". [2] It is a binary form for representing simple or complex data structures including associative arrays (also known as name-value pairs), integer indexed arrays, and a suite of fundamental scalar types.
Go's foreach loop can be used to loop over an array, slice, string, map, or channel. Using the two-value form gets the index/key (first element) and the value (second element): for index , value := range someCollection { // Do something to index and value }
The most significant new feature is support for functions as first-class values. [5] XPath 3.0 is a subset of XQuery 3.0, and most current implementations (April 2014) exist as part of an XQuery 3.0 engine. XPath 3.1 became a Recommendation on 21 March 2017. [6] This version adds new data types: maps and arrays, largely to underpin support for ...
.MAPs are also identified as color maps. An example of such software that supports .map files is SoundSpectrum's G-Force music visualizer. Another form of the .MAP file is for HTML image maps. An image map is formatted in HTML and creates click-able areas over a provided image. More generically, the .MAP extension can be used to denote any file ...
