@DaveA: thanks for pointing it out.
For a origin-centre circle x**2 + y**2 = r**2, I assumed r to be integer,
however it was r**2 which was integer. A mistake on my part.

No, I'm trying to find all integer co-ordinates which lies on a circle.
Say for a circle of radius 5 the co-ordinates are [(5, 0), (0, 5), (-5, 0),
(0, -5), (3, 4), (4,3), (3, -4), (4, -3), (-3,
4), (-4

Your "all possible results" isn't even close to all the points that match
the 0<= r <= 5. And I don't know how either spec justifies the set logic
you quoted.
So I have to start over. I think you're trying to find all integer
co-ordinates which lie on or within

radius 'r'.
If given the upper bound of 'r', I want to calculate all given co-ordinates
lying for 0 <= r <= n
Let's say the upper bound of radius is 5
All possible results are:
radius 'r' - (x, y)
0
How to find all possible integer co-ordinates lying on a circle of given
radius 'r'.
If given the upper bound of 'r', I want to calculate all given co-ordinates
lying for 0 <= r <= n
Let's say the upper bound of radius is 5
All possible results are:
radius 'r' - (x, y)
0 - (0, 0)
1 - (1, 0), (0, 1
