Since :+ I believe that this is the shortest entry from any language that wasn't designed for golfing. The RealFloat subclass of Floating and RealFrac provides Don't reinvent the wheel, always use a library when available. (bounded, machine integers, with a range equivalent to at least In the Lyon and Grenoble metropolitan areas, and the Haute-Savoie department, INRAE units contribute to research activities at the Lyon-Saint-Etienne, Grenoble-Alpes, and Savoie Mont Blanc . The further subclass Is there a place where we can find the Haskell library for Marlowe? What information do I need to ensure I kill the same process, not one spawned much later with the same PID? Here is my attempt: intSquareRoot :: Int -> Int intSquareRoot n | n*n > n = intSquareRoot (n - 1) | n*n <= n = n I'm guessing its not working because n decreases along with the recursion as required, but due to this being Haskell you can't use variables to keep the original n. and obtain all kinds of wrong results. (E.g. Since the largest possible product is the root-so-far with the square of a single digit, it should be able to take the square root of up to 120-bit or so numbers on a 64-bit system. BTW, this isn't (but should be) in the form of a function, as mentioned in the problem statement. If you're using C/C++, you may assume the existence of unsigned 64-bit and 32-bit integer types, e.g.. One of the thing that confused me was that I expected 500 to be an Int, but in fact the literals are automatically converted to a correct Num instance. Neat idea, it can also be represented in J in the exact same character count: @us: Go ahead. There are special cases for converting from Rationals: This is an inherently lossy transformation since integral types cannot express non-whole numbers. Essentially, the programmer has specified that x should be squared, but has not specified whether it should be squared with an Int or an Integer value of two. fromIntegral The library is optimized and well vetted by people much more dedicated to efficiency then you or I. Code Review Stack Exchange is a question and answer site for peer programmer code reviews. The most commonly used integral types are: The workhorse for converting from integral types is fromIntegral, which will convert from any Integral type into any Numeric type (which includes Int, Integer, Rational, and Double): For example, given an Int value n, one does not simply take its square root by typing sqrt n, since sqrt can only be applied to Floating-point numbers. Is there a way to use any communication without a CPU? sqrt x = x ** 0.5 I found that I could substitute x ** 0.5 for sqrt which tells me a lot about Haskell. I'll try to fix it. If their sum is greater than the latter, then I subtract the first coefficient with the second and add the third, otherwise I show the result by halving the second coefficient and adding the third. Learn more about Stack Overflow the company, and our products. that the implementation of the abstract data type must maintain; it is Edit 3: Saved six more bytes thanks to proudhaskeller! In this case the compiler will probably have to generate sqrt and double multiplication in software, and you could get advantage in optimizing for your specific application. Sometimes you shouldn't divide problems into too small parts (like checks is_square): There's a very simple way to test for a perfect square - quite literally, you check if the square root of the number has anything other than zero in the fractional part of it. To compute 5, for instance, we can simply type the following into the interpreter, and it would print back the return value. Dystopian Science Fiction story about virtual reality (called being hooked-up) from the 1960's-70's. Andrew Lelechenko andrew dot lelechenko at gmail dot com. Interesting features of Haskell: truly functional lazy evaluation -- can deal with infinite structures (semantically the same as call by name) type system -- statically typed, no type declarations needed; polymorphic future of functional languages . the integer square root of 7 is 2, and that of 9 is 3). Is there a better way to write a "string contains X" method? Fixing this to give the correct answer for input, you can replace (div x 2 + rem x 2) with div(x+1)2, at your "half" function, I actually have a solution of my own which has 49 characters, and solves in O(log n), but i only have 2 upvotes ;-(. but it didn't work and I needed to use parenthesis. classes are standard, the default list is consulted, and the first For example, Code Golf Stack Exchange is a question and answer site for programming puzzle enthusiasts and code golfers. n The integer square root of a positive integer n is the largest integer whose square is Nice work! How do you execute this for a given integer? What is the difference between these 2 index setups. It should work just fine for larger integer values too as long as the a=32 part is changed to a=NUMBITS/2. Lesson 3 - unsure how "sigs" is created or where txInfoSignatories comes from or how it works, Continue to be utterly disoriented as to where these magic words come from and how they might be connected. It will be better to start from 0 up to the solution, which improves complexity to O(sqrt n): But here is a much more efficient code using Babylonian method (Newton's method applied to square roots): It is not as fast as Pedro Rodrigues solution (GNU's multiprecision library algorithm), but it is much simpler and easier to understand. @mbomb007 Fair enough - Headline edited. As pointed out by other answer, there is still a limitation of big integers, but unless you are going to run into those numbers, it is probably better to take advantage of the floating point hardware support than writing your own algorithm. of a given type can be specified in an Integral or Fractional For example: hypotenuse 500 0 --result:500 :: Int Answer: In principle you can define a type like data GenericNumber = Integer Integer | Rational Rational | Double Double and define appropriate instances for Num class et. value of two. Not the answer you're looking for? negate,abs::(Numa)=>a->a m the integer square root of 7 is 2, and that of 9 is 3). The first coordinate system, which ill call coord1, starts in the upper left at (0, 0) and ends in the lower right at (500, 500). toRational::(RealFraca)=>a->Rational By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. When expanded it provides a list of search options that will switch the search inputs to match the current selection. Does CJam have arbitrary-precision decimals, to cover the whole input range? Real polynomials that go to infinity in all directions: how fast do they grow? Can someone please tell me what is written on this score? Welcome to Code Golf and Coding Challenges Stack Exchange! There's an index link in the upper right where you can look up specific functions and then, on each module's documentation page, there are links to source code. Integral instance will do, whereas here, very different behavior Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Add details and clarify the problem by editing this post. YA scifi novel where kids escape a boarding school, in a hollowed out asteroid. Without outright stating the solution, here are some functions you may find handy: The details of your hypotenuse function are up to you, so I will leave the implementation to your discretion. min2Cycle. Where is the Haskell course mentioned by Lars? You might be able to shave off a character by changing, @ToddLehman That actually happens to be fixed-point arithmetic (, Ok, that is just cool. I was thinking too much in terms of C when I posted the question. In the golfed code, that translates to replacing f$map fst with fst$f, saving 4 more bytes. What's the way to determine if an Int is a perfect square in Haskell? Surely the last |0 truncates any value to 32 bit. Return value It returns a floating-point value. The best answers are voted up and rise to the top, Not the answer you're looking for? Thank you @Matthias Sieber From your instructions, I was delighted to find the following in the source code. more serious than the exponentiation ambiguity, because there, any Checks all numbers from n to 0, giving the first one where x^2 <= n. Runtime is O(n - sqrt n), this solution implements the newton-raphson method, although it searches integers instead of floats. (c) 2011 Daniel Fischer, 2016-2021 Andrew Lelechenko. ), Here are a few test cases (with a bit of extra output I used to track the time). sqrt is a very expensive operation in most programming languages, whereas multiplication is a single assembly instruction as long as we're using native CPU integers. What part of Hindley-Milner do you not understand? So, simply saying. mathematical integers, also known as "bignums") and Int (integerSquareRoot) Connect and share knowledge within a single location that is structured and easy to search. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, I like this solution very much. That's great thanks! Why does awk -F work for most letters, but not for the letter "t"? Here is an ungolfed version: Edit: Saved two bytes by replacing the "otherwise" clauses with "0<1" as a shorter version of "True", and a few more by inlining g*g. Also, if you are happy with O(sqrt(n)) you could simply do. of Num, however, is a subclass of Ord as well. My first try at code golf. It is very slow for large numbers, complexity is O(n). account for numerator,denominator::(Integrala)=>Ratioa->a. I thought that it was a good exercise in trying to make it reasonable and capable of being generalized since the cube root uses coefficients 1000, 300, 30 and 1, with the number having to be checked for its magnitude one thousand at a time. I don't know whether it's the most efficient or not. How do two equations multiply left by left equals right by right? It names a function s with parameter a and returns one minus the first number whose square is greater than a. Definitely appreciated. This process of stepping down by 1 continues until you reach 0. Why are parallel perfect intervals avoided in part writing when they are so common in scores? We outline here the basic characteristics of the Won't the script just stop? We normally score APL as one byte per character. rmsxy=sqrt((x^(2::Integer)+y^(2::Integer))*0.5) What information do I need to ensure I kill the same process, not one spawned much later with the same PID? programmer has specified that x should be squared, but has not By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. function, so this name is provided instead. Think of it this way, if you have a positive int n, then you're basically doing a binary search on the range of numbers from 1 .. n to find the first number n' where n' * n' = n. I don't know Haskell, but this F# should be easy to convert: Guaranteed to be O(log n). What to do during Summer? type from the list that will satisfy the context of the type variable By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The proposed solution doesn't work because overlaps the n parameter in each recursion call. In Haskell, we can convert Int to Float using the function fromIntegral. So, I came up with a pretty clever alternative, Very simple. Lisp [8]. If not for it, I could do 18 chars. fractional parts, and a collection of functions that round to Here, we have declared our function in the first line and in the second line, we have written our actual function that will take two arguments and produce one integer type output. I have a simple function, which is to get the Maybe there is a common simple way to implement such a predicate? Why is a "TeX point" slightly larger than an "American point"? Making statements based on opinion; back them up with references or personal experience. How to implement decimal to binary conversion. And is it usual to have that many compositions in one line? Since I am studying a function that uses sqrt, I want to see how that was made in Haskell. In Haskell, functions are defined exactly like the numbers and strings we've already seen, with a few bits of syntactic sugar to make it easier. It also needs to use an internal recursion in order to keep the original n. To make it complete, I generalized it to any Integral type, checked for negative input, and checked for n == 0 to avoid division by 0. janv. One particular doubt I have is in the use of $ in toPerfectSquare, that I first used . Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. b, above), if at least one of its classes is numeric and all of its +2 characters to assign the function to a variable for benchmarking: The cheap/brilliant exponentiation trick: which also happens to be very fast (although not as fast as the built-in): Translation of my Forth submission. Integral. Easy to modify perfect cubes and higher powers. btw I can't understand why memorizing pure functions is not a part of haskell. Is "in fear for one's life" an idiom with limited variations or can you add another noun phrase to it? Example 12 = 2 x 2 x 3; 2 appears twice (even number of times) but 3 just once (odd number of times), so the number I need to multiply 12 by to get a perfect square is 3. than that of multiplication.)]. advantage that the method of interpreting a numeral as a number Storing configuration directly in the executable, with no external config files. exponentiation operators with different typings, see report section 6.8.5) has RealFloat instance of fromInteger. https://gitlab.haskell.org/ghc/ghc/-/blob/master/libraries/base/GHC/Float.hs, The philosopher who believes in Web Assembly, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI, do you need to know Haskell to code in marlowe, Launch.json for VSCode/Haskell? a limited subset of integers without precision loss.

What kind of tool do I need to change my bottom bracket? It will be better to start from 0 up to the solution, which improves complexity to O(sqrt n): But here is a much more efficient code using Babylonian method (Newton's method applied to square roots): It is not as fast as Pedro Rodrigues solution (GNU's multiprecision library algorithm), but it is much simpler and easier to understand. The explicit type signature is legal, A GenericNumber type would also negate the type safety that strongly typed numbers provide, putting the burden back on the programmer to make sure they are using numbers in a type-safe way. If your langauge does not support 64-bit integers (for example, Brainfuck apparently only has 8-bit integer support), then do your best with that and state the limitation in your answer title. Find centralized, trusted content and collaborate around the technologies you use most. (The last test case is too big for Powershell's normal Int64 type, by the way! Thank you. Try it online.

Edit 2: I just realized that since pairs are sorted by dictionary order, instead of doing min2Cycle . Unless the challenge specifies it, there is no need to count in UTF-8. such that Fixing this is easy: isSquare :: Int -> Bool isSquare x = let x' = truncate $ sqrt (fromIntegral x :: Double) in x'*x' == x. Review invitation of an article that overly cites me and the journal, Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. However, O(log n) is misleading. +1. component extraction functions are provided: ), @MartinEnder Thanks for the warm welcome and tips :), Ah yes. In your choice of language, write the shortest function that returns the floor of the square root of an unsigned 64-bit integer.

Tested on OS X (64 bit). the ordinary division operator (/). Even though this algorithm executes in roughly half as many steps as the abacus algorithm, it has a runtime that's about 5 times slower than the abacus algorithm when I benchmark it on my Core i7 CPU, which doesn't like doing division. Of course, GHC is not the only implementation of Haskell, but at least within these realms, both terms are most often used as synonyms. Also, bookmark this, the top-level of the latest API docs: https://downloads.haskell.org/~ghc/latest/docs/html/libraries/index.html. signature has the effect of restricting inc's type, and in this Uh, looks like the last test case crashes.

Integer square root function in Haskell Ask Question Asked 9 years, 5 months ago Modified 1 year ago Viewed 17k times 5 The integer square root of a positive integer n is the largest integer whose square is less than or equal to n. (E.g. It doesn't have to be named. floating-point. properFraction::(Fractionala,Integralb)=>a->(b,a) Provides a named function, s, which calculates the square root by filtering the list from 0 to n for the square being larger than the input, then prints the last such number. Runs incredibly slowly (O (sqrt n), maybe?). The standard types Float and Double fall in class RealFloat. Since this is a code-golf (and I'm terrible with maths), and runtime is merely a suggestion, I've done the naive approach that runs in linear time: Of course, it's terribly slow for larger inputs. fromRational::(Fractionala)=>Rational->a Peanut butter and Jelly sandwich - adapted to ingredients from the UK. You could try to use other computation methods to replace the sqrt and the multiplication with just integer arithmetic and shifts, but chances are it is not going to be faster than one sqrt and one multiplication. So, lambda functions are fine. What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993?
