hi,
if you have a circle between two circles is a line drawn and to keep the circle drawn from a list we use.
and we want to keep them where the line drawn between the use of a list.
how can we define this list?
and how well did the comparison between the two list?
compare that to do this we determine the proximity of two circles and two diffrent colors to give it.
