For "one-dimensional" (single-indexed) arrays – vectors, sequences, strings etc. – the most common slicing operation is extraction of zero or more consecutive elements. If we have a vector containing elements (2, 5, 7, 3, 8, 6, 4, 1), and want to create an array slice from the 3rd to the 6th elements, we get (7, 3, 8, 6).
PowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language.Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.

A typical alternative for dense array storage is to use Iliffe vectors, which typically store pointers to elements in the same row contiguously (like row-major order), but not the rows themselves. They are used in (ordered by age): Java , [ 14 ] C# / CLI / .Net , Scala , [ 15 ] and Swift .
sizeof can be used to determine the number of elements in an array, by dividing the size of the entire array by the size of a single element. This should be used with caution; When passing an array to another function, it will "decay" to a pointer type. At this point, sizeof will return the size of the pointer, not the total size of the array.
Structure of arrays (SoA) is a layout separating elements of a record (or 'struct' in the C programming language) into one parallel array per field. [1] The motivation is easier manipulation with packed SIMD instructions in most instruction set architectures, since a single SIMD register can load homogeneous data, possibly transferred by a wide internal datapath (e.g. 128-bit).
PowerShell: The New-Item cmdlet of Windows PowerShell that can create empty files, folders, junctions, and hard links. [3] In PowerShell 5.0 and later, it can create symbolic links as well. [ 4 ] The Get-Item and Get-ChildItem cmdlets can be used to interrogate file system objects, and if they are NTFS links, find information about them.
An array with stride of exactly the same size as the size of each of its elements is contiguous in memory. Such arrays are sometimes said to have unit stride. Unit stride arrays are sometimes more efficient than non-unit stride arrays, but non-unit stride arrays can be more efficient for 2D or multi-dimensional arrays, depending on the effects ...
The Get-ChildItem (also available through the aliases ls, dir or gci) retrieves the child keys of the current location. By using the Set-Location (or the alias cd ) command the user can change the current location to another key of the registry. [ 28 ]
