In computer science, an array is a data structure consisting of a collection of elements (values or variables), of same memory size, each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula. [1][2][3] The simplest type of data ...
In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition. Conditionals are typically implemented by ...
This article is about the data structure operation. For other uses of slicing, see Slicing (disambiguation). In computer programming, array slicing is an operation that extracts a subset of elements from an array and packages them as another array, possibly in a different dimension from the original. Common examples of array slicing are ...
A sparse matrix obtained when solving a finite element problem in two dimensions. The non-zero elements are shown in black. In numerical analysis and scientific computing, a sparse matrix or sparse array is a matrix in which most of the elements are zero. [1] There is no strict definition regarding the proportion of zero-value elements for a ...
Iterator. In computer programming, an iterator is an object that progressively provides access to each item of a collection, in order. [1][2][3] A collection may provide multiple iterators via its interface that provide items in different orders, such as forwards and backwards. An iterator is often implemented in terms of the structure ...
In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map. Switch statements function somewhat similarly to the if statement used in programming languages like C / C++, C#, Visual Basic .NET ...

e. In computer science, a skip list (or skiplist) is a probabilistic data structure that allows average complexity for search as well as average complexity for insertion within an ordered sequence of elements. Thus it can get the best features of a sorted array (for searching) while maintaining a linked list -like structure that allows ...
