For instance, when mapping the three-dimensional array A[P][N][M] to a linear array L[M⋅N⋅P], both with M ⋅ N ⋅ P elements, the index r in the linear array to access a specific element with L[r] = A[z][y][x] in zero-based indexing, i.e. [0 ≤ x < P], [0 ≤ y < N], [0 ≤ z < M], and [0 ≤ r < M ⋅ N ⋅ P], is calculated by
a = [3, 1, 5, 7] // assign an array to the variable a a [0.. 1] // return the first two elements of a a [.. 1] // return the first two elements of a: the zero can be omitted a [2..] // return the element 3 till last one a [[0, 3]] // return the first and the fourth element of a a [[0, 3]] = [100, 200] // replace the first and the fourth element ...
A simple and inefficient way to see where one string occurs inside another is to check at each index, one by one. First, we see if there is a copy of the needle starting at the first character of the haystack; if not, we look to see if there's a copy of the needle starting at the second character of the haystack, and so forth.
In computer science, an algorithm for matching wildcards (also known as globbing) is useful in comparing text strings that may contain wildcard syntax. [1] Common uses of these algorithms include command-line interfaces, e.g. the Bourne shell [2] or Microsoft Windows command-line [3] or text editor or file manager, as well as the interfaces for some search engines [4] and databases.

Yalda Night, or Shab-e Yalda (also spelled Shabe Yalda), marks the longest night of the year in Iran and in many other Central Asian and Middle Eastern countries. On the winter solstice, in a ...

In array languages, operations are generalized to apply to both scalars and arrays. Thus, a+b expresses the sum of two scalars if a and b are scalars, or the sum of two arrays if they are arrays. An array language simplifies programming but possibly at a cost known as the abstraction penalty.
