String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
A quine's output is exactly the same as its source code. A quine is a computer program that takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs".
To use Unicode in the domain part of email addresses, IDNA encoding must traditionally be used. Alternatively, SMTPUTF8 [3] allows the use of UTF-8 encoding in email addresses (both in a local part and in domain name) as well as in a mail header section. Various standards had been created to retrofit the handling of non-ASCII data to the ...
An array data structure can be mathematically modeled as an abstract data structure (an abstract array) with two operations get(A, I): the data stored in the element of the array A whose indices are the integer tuple I. set(A, I, V): the array that results by setting the value of that element to V. These operations are required to satisfy the ...

In Ruby, symbols can be created with a literal form, or by converting a string. [1] They can be used as an identifier or an interned string. [10] Two symbols with the same contents will always refer to the same object. [11] It is considered a best practice to use symbols as keys to an associative array in Ruby. [10] [12]
A computer program is a sequence or set [a] of instructions in a programming language for a computer to execute.It is one component of software, which also includes documentation and other intangible components.
A range specification can return a point to a single character, or a slice of the string. Strings can be indexed from either the right or the left. Positions within a string are defined to be between the characters 1 A 2 B 3 C 4 and can be specified from the right −3 A −2 B −1 C 0. For example,
