Is SQL Turing-complete?

Yes, it is Turing complete. T-SQL is declarative--but also--an imperative language.

What is meant by Turing-complete?

Practically, what you need to know is that a Turing-complete language (also called a universal language) is one where you can compute anything that any other computational method can compute. In other words, a language that's non-universal—or Turing incomplete—has some limits on the set of things that it can compute.

Is Postgres SQL Turing-complete?

It's semi-common knowledge that Postgres' dialect of SQL is Turing complete. This means any program you can write in a general purpose programming language, you can also write in SQL.

How do you calculate Turing completeness?

Typically, one proves a given language is Turing-complete by providing a recipe for translating any given Turing machine program into an equivalent program in the language in question. Alternately, one can provide a translation scheme from another language, one that has already been proven to be Turing-complete.

Is Haskell Turing complete?

Haskell is Turing complete, just like any other programming language. There are programming languages that aren't Turing complete - mostly 'total' languages or proof assistants - but Haskell is not one of them.

Is JSON Turing complete?

The notion of Turing completeness does not apply to languages such as XML, HTML, JSON, and YAML, because they are typically used to represent structured data, not describe computation.

Is Turing complete PDF?

With no recursion and no unbounded loops, PDF is clearly not Turing complete.

Is minesweeper Turing complete?

"Some Minesweeper Configurations". "Infinite Versions of Minesweeper are Turing-complete".

How are C++ templates Turing complete?

To prove that C++ templates are Turing-complete, we constructed a higher-order functional programming language out of them. The language supports higher-order functions, literal values (raw types), natural numbers (as types), booleans and conditionals.

Is HTML and CSS Turing complete?

A programming language is Turing complete if it equivalent to a Turing machine. In practice, it means that any algorithm can be implemented. Apparently, HTML5 + CSS3 is now also Turing complete because it can be used to program a Rule 110 automaton.

Is the universe Turing complete?

> Is our universe Turing-complete? No! A Turing machine [ https://en.m.wikipedia.org/wiki/Turing_machine ] is a mathematical model that requires an unbounded number of memory cells. Despite its size the observable universe is very definitely finite and therefore cannot contain an infinite memory tape.

How is Minesweeper Turing complete?

The proof was by making suitable minesweeper configurations simulate digital computers, with logic gates such as and and not gates. This is reminiscent of John Conway's game of life [2] which was proved to be Turing complete by similar means [1].

Is the bash shell Turing complete?

The language of Bash commands is a Turing-complete programming language, meaning that if it is even theoretically possible for a given computation to be performed, then it is theoretically possible to perform it in Bash.

Is SML Turing complete?

Generally speaking, whether or not a language is Turing Complete has nothing to do with whether it has Arrays. Functional languages like SML and Haskell lack arrays, just like Lambda Calculus, and these are actually useful languages!

Is Lua Turing complete?

Thus most programming languages are turing complete. C, C++, C#, Java, Lua, Python. They are all turing complete. Your regular languages and markup languages are usually not turing complete.

Is Yaml Turing complete?

YAML is not turing complete and is hence not "code". YAML has a few oblique gotchas but they don't affect the fundamental suitability of it for this purpose. Once you get used to it, space indentation becomes a feature, not a bug.

How do you play Minesweeper?

0:001:22How to play Minesweeper - YouTubeYouTube

Is C++ preprocessor Turing complete?

the preprocessor is not Turing complete, at least not if the program is preprocessed only once. This is true even if the program is allowed to include itself.

Are templates Turing complete?

Template metaprogramming is Turing-complete, meaning that any computation expressible by a computer program can be computed, in some form, by a template metaprogram. Templates are different from macros.

Is Sass Turing complete?

sass is a library of functions for functional programming in Sass. Sass is Turing complete and has rich data structures such as lists and maps, that allows it to do much more than CSS templating.

Are human languages Turing complete?

No, natural languages aren't Turing complete in the same way onions are not. Quoting Wikipedia: A computational system that can compute every Turing-computable function is called Turing-complete (or Turing-powerful).

Is Lisp Turing complete?

All general-purpose languages are Turing-complete. It doesn't take that much to be Turing-complete. But there's something that most languages don't address that Lisp does. You can break up Turing-completeness into two parts: one is that it can compute any computable function.

What's the difference between Bash and shell?

bash is a superset of sh. Shell is a command-line interface to run commands ad shell scripts. Shells come in a variety of flavors, much as operating systems come in a variety of flavors. So, Shell is an interface between the user and the operating system, which helps the user to interact with the device.

Is bash the same as shell?

5 Answers. Bash ( bash ) is one of many available (yet the most commonly used) Unix shells. Bash stands for "Bourne Again SHell", and is a replacement/improvement of the original Bourne shell ( sh ). Shell scripting is scripting in any shell, whereas Bash scripting is scripting specifically for Bash.

Is Prolog Turing complete?

Pure Prolog is based on a subset of first-order predicate logic, Horn clauses, which is Turing-complete.

What does 3 mean in Minesweeper?

The numbers on the board represent how many bombs are adjacent to a square. For example, if a square has a "3" on it, then there are 3 bombs next to that square. The bombs could be above, below, right left, or diagonal to the square.

Can you lose Minesweeper first click?

Yes, the original Minesweeper never allows you to lose on the first click. This version is an extension of that behavior: it will “cheat” in your favor anytime you are forced to guess (not just on the first move).

Is C macro Turing complete?

The C preprocessor is not Turing-complete, but it comes very close: recursive computations can be specified, but with a fixed upper bound on the amount of recursion performed. However, the C preprocessor is not designed to be, nor does it perform well as, a general-purpose programming language.

What games are Turing complete?

Unintentional Turing completenessDwarf Fortress.OpenTTD.Terraria.Minecraft.Minesweeper.LittleBigPlanet.Baba is You.Factorio.

Is C++ Turing complete?

C++ templates are a Turing-complete language [30] , and thus they allow arbitrary computations on types and constants to be performed at compile time.

Is Sass and SCSS same?

SASS (Syntactically Awesome Style Sheets) is a pre-processor scripting language that will be compiled or interpreted into CSS. SassScript is itself a scripting language whereas SCSS is the main syntax for the SASS which builds on top of the existing CSS syntax.

Is HTML5 Turing complete?

A programming language is Turing complete if it equivalent to a Turing machine. In practice, it means that any algorithm can be implemented. Apparently, HTML5 + CSS3 is now also Turing complete because it can be used to program a Rule 110 automaton.

Is SED Turing complete?

Turns out sed is a tiny assembly language that has a comparison operation, a branching operation and a temporary buffer. These operations make sed Turing complete.
