[7] The modern formulation of the algorithm as three nested for-loops was first described by Peter Ingerman, also in 1962.[8]. By default, unique saves the last unique value it finds, and the output will be sorted. For example: Currently I have a very inefficient and incomplete approach, using the unique function and various for loops and if statements, but feel that there should be a simple answer.
