Write here again: I find an easier non-recursive solution to compute the rectangle number (represented as RN) of an h x w rectangle (which has a height of h units and a width of w units):
Situation 1: If (h and w are coprime) or (h = 1) or (w = 1) then RN = h + w - 1. Situation 2: If h and w are not relatively prime, we can find the greatest common divisor (represented as gcd) that makes (1) h = h' x gcd, w = w' x gcd and (2) (h' and w' are coprime) or (h' = 1) or (w' = 1), then we finally get the result RN = (h' + w' - 1) x gcd. This computation method will obviously help you find all the rectangles with a given pair of height and width. It's pretty much like a reverse problem. -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
