Composite data types | Abstract data types | Data types
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. It supports 'lookup', 'remove', and 'insert' operations. The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays.The two major solutions to the dictionary problem are hash tables and search trees.In some cases it is also possible to solve the problem using directly addressed arrays, binary search trees, or other more specialized structures. Many programming languages include associative arrays as primitive data types, and they are available in software libraries for many others. Content-addressable memory is a form of direct hardware-level support for associative arrays. Associative arrays have many applications including such fundamental programming patterns as memoization and the decorator pattern. The name does not come from the associative property known in mathematics. Rather, it arises from the fact that values are associated with keys. It is not to be confused with associative processors.

This video introduces the concept of phased arrays. An array refers to multiple sensors, arranged in some configuration, that act together to produce a desired sensor pattern. With a phased array, we can electronically steer that pattern without having to physically move the array simply b

Determine if the Binary Operation Defined by the Table is Commutative and Associative
In this video we determine whether or not a binary operation is commutative and associative. The binary operation is actually defined by a table in this example. I hope this video helps someone.

Array Variables - Introduction
This video introduces array variables. It defines an array variable as a named group of contiguous memory locations, each element of which can be accessed by means of an index number. It explains the difference between one dimensional and two dimensional arrays, and covers how these can

In this video, I discuss the concept of "associative arrays" in JavaScript. I look at how JavaScript objects are collections of name-value (or key-value) pairs. This works in much the same as dictionaries in Python or HashMaps in Java. This concecpt will come extremely handy in the codi
