/*Computer generated file to remove duplicates. Since Thrust's unique and sort, unlike their std's counterparts, don't have a way to specify the size of each element in
the array, comparing pairs, triplets and other sets is not possible without defining a new pointer and all related operations for each set. If you have a better idea to do
this, please don't hesitate to email us.*/
