Problem Statement

A list comprehension is a special syntax in some programming languages to describe lists. It is similar to the way mathematicians describe sets, with a set comprehension, hence the name. Some attributes of a list comprehension are:

Write a list comprehension that builds the list of all Pythagorean triples with elements between   1   and   n. If the language has multiple ways for expressing such a construct (for example, direct list comprehensions and generators), write one example for each.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm List comprehensions step by step in the Icon and Unicon programming language

Source code in the icon programming language

    |(x := seq(), x^2 > 3, x*2)


   procedure main()
      every write(|(x := seq(), x^2 > 3, x*2) \ 100
   end


procedure main(a)
    n := integer(!a) | 20
    s := create (x := 1 to n, y := x to n, z := y to n, x^2+y^2 = z^2, [x,y,z])
    while a := @s do write(a[1]," ",a[2]," ",a[3])
end
