Let's start with the solution:
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
andNode
. TheLeaf
constructor takes a single value of typea
and theNode
constructor takes a list of trees of typea
. -
Foo is a type class that defines a single method called
bar
. This method takes a value of typea
and returns a value of typeb
.

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

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
