/*

 * For a giving array of ranges of positive numbers in any size and in any order, find a solution for the following:

 * 

 *  1. externd the ranges if they are contiguous or overlapping.

 *  2. then give the output of all distinct non-contiguous ranges

 *  

 *  E.g.:

 *  Input:  (4, 8), (3, 6), (10, 20), (20, 25)

 *  Output: (3, 8), (10, 25)
