How to find the intersection between a set of two ranges of number.
let me explain the question with an example,
{2,3} {3,8} would result to 0 {2,5} {3,8} would result to 2 {3,6} {3,8} would result to 3 {4,5} {3,8} would result to 1 {4,5} {3,8} would result to 1 {8,9} {3,8} would result to 0
Note:This could be easily done with series of if in a computer application, I am hungry for a mathematical solution!
