This is my problem. I have a scale from 0 to 15 and five different
elements with their own position on that scale. How can I understand if
they are spread all over the scale, have different positions on the
scale, or if they are close and nearby each-other?
These are close: 2,3,4,3,2
These are not so close: 2,4,3,12,15
These are spread: 0,5,8,12,15
