For loop and ranges → The roots of equation

README.md

There are numbers a,b,c,d. Output in ascending order all the integers between 0 and 1000 (inclusively), which are the roots of the equation

a⋅x^3 + b⋅x^2 + c⋅x + d = 0

If a specified interval does not contain any roots of the equation, do not output anything.
