Detailed Description

Implementation for the Union of two sorted Arrays algorithm.

The Union of two arrays is the collection of all the unique elements in the first array, combined with all of the unique elements of a second array. This implementation uses ordered arrays, and an algorithm to correctly order them and return the result as a new array (vector).
