From: draq Date: 2005-12-12T06:57:38+09:00 Subject: Calculating single-digit summands I have tried to make an algorithm that finds all possible combinations of single-digit summands for a number. After an afternoon of hard and desperate work I got something inefficient (although it works). Maybe someone has a better idea.
