In computer science, a multimap (sometimes also multihash, multidict or multidictionary) is a generalization of a map or associative array abstract data type in which more than one value may be associated with and returned for a given key. Both map and multimap are particular cases of containers (for example, see C++ Standard Template Library ...
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.
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.
DART utilizes a hub and spoke system, designed to favor commuters, as opposed to point-to-point system. [8] The network was redesigned in 2012 to utilize the new DART Central Station, which most local and express routes terminate at or pass through. A secondary hub around Valley West Mall connects multiple western routes. A northern crosstown ...
MAX, officially DART Express Bus Route 221, [1] ran from 5:30 a.m. to 11:30 p.m. on weekdays, [2] at a frequency of approximately 30 minutes and 18 daily departures. [1] [3] The route traveled south from CentrePort/DFW Airport station on State Highway 360 to Division Street, where it turned west and stopped at Six Flags Over Texas. Buses ...
For a more comprehensive listing of data structures, see List of data structures. The comparisons in this article are organized by abstract data type . As a single concrete data structure may be used to implement many abstract data types, some data structures may appear in multiple comparisons (for example, a hash map can be used to implement ...
Therefore, compilers will attempt to transform the first form into the second; this type of optimization is known as map fusion and is the functional analog of loop fusion. [2] Map functions can be and often are defined in terms of a fold such as foldr, which means one can do a map-fold fusion: foldr f z . map g is equivalent to foldr (f .
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel and distributed algorithm on a cluster. [1] [2] [3]A MapReduce program is composed of a map procedure, which performs filtering and sorting (such as sorting students by first name into queues, one queue for each name), and a reduce method, which performs a summary ...
