So, I was looking at the question here, and built a rather ugly solution for the problem.While trying to clean it up, I started investigating list comprehensions and the list monad.What I decided to d
I am doing question 266 at Project Euler and after a bit of searching, found this method of quickly finding the factors of a number. What you do is find all the permutations of the prime factors of a
I\'m writing a haskell wrapper for a c++ library and as much as I can impo开发者_如何学Pythonrt functions from the library to my haskell program, I have no clue how to import c++ data types. For insta
Suppose that I have two data types Foo and Bar.Foo has fields x and y.Bar has fields x and z.I want to be able to write a function that takes either a Foo or a Bar as a parameter, extracts the x value
The following code is in Haskell. How would I write similar function in C#? squareArea xs = [pi *开发者_如何学Go r^2 | r <- xs]
Is it generally considered a bad practice to use non-exhaustive pattern machings in functional languages like Haskell or F#, which means that the cases specified don\'t cover all possible input cases?
I wish to draw individual pixels on a screen in a window or something f开发者_运维问答or real-time display in haskell.
I am doing question 62 at project euler and came up with the following to test whether a number is cubic:
I understand that: head (map (2**) [1..999999]) Will only actually evaluate 2**1, and none of the rest, but the book I am reading says that:
