Step by Step solution about How to resolve the algorithm Documentation step by step in the Haskell programming language

This is a Haskell source code file that defines several functions and a data type.

  • square1 is a function that takes an integer and returns the square of that integer. It is defined using the x * x syntax.

  • square2 is another function that takes an integer and returns the square of that integer. It is also defined using the x * x syntax, but it has a documentation comment that spans multiple lines.

  • square3 is a function that takes an integer and returns the square of that integer. It is defined using the x * x syntax, but it has a documentation comment that is placed underneath the function definition.

  • square4 is a function that takes an integer and returns the square of that integer. It is defined using the x * x syntax, but it has a documentation comment that is written as a Haskell block comment.

  • Tree is a data type that represents a tree data structure. It has two constructors: Leaf and Node. The Leaf constructor takes a single value of type a and the Node constructor takes a list of trees of type a.

  • Foo is a type class that defines a single method called bar. This method takes a value of type a and returns a value of type b.

Source code in the haskell programming language

-- |This is a documentation comment for the following function
square1 :: Int -> Int
square1 x = x * x

-- |It can even
-- span multiple lines
square2 :: Int -> Int
square2 x = x * x

square3 :: Int -> Int
-- ^You can put the comment underneath if you like, like this
square3 x = x * x

{-|
  Haskell block comments
  are also supported
-}
square4 :: Int -> Int
square4 x = x * x

-- |This is a documentation comment for the following datatype
data Tree a = Leaf a | Node [Tree a]

-- |This is a documentation comment for the following type class
class Foo a where
    bar :: a
